In this PHP tutorial we will see how to start Session in PHP.

PHP Session

A session is a process to store information (in variables) and further to be used this information across multiple pages. Beside in session, the information is not stored on the user’s computer, unlike a cookie.

A session creates a file in a directory on the server for a short period of time where registered session variables and their values are stored. This type of data will be available to all pages on the site during that visit.

And you can find out the location of the temporary directory file is determined by a setting in the php.ini file which is called session.save_path.

What is a PHP Session?

We understood “what is PHP Session?” through an example. Let’s suppose we are working with an application, first we open it, do some task and then close the application.

This process is similar like a Session. When we follow these processes, the computer knows who we are. And it also knows when we start the application and when we close the application.

But when we use internet, there is one issue by storing user information to be used across multiple pages (e.g. usernames, email, etc). By default, session data last until the user closes the browser.

How to Start a PHP Session

A session is simply started with the using of session_start() function.

A PHP session variables are hold in associative array which is define by $_SESSION[]. These hold information can be retrieved during lifetime of a session.

<?php
// Start the session
session_start();
?>

Let’s see an example. First we create a page “session-demo.php”. In this new page, we start a new PHP session and define some session variables:

<?php
// Start the session
session_start();
?>
<!DOCTYPE html>
<html>
<body>

<?php
// Set session variables
$_SESSION["firstname "] = "abc";
$_SESSION["email"] = "test@gmail.com";
echo 'Hi, ' . $_SESSION["firstname"] . ' ' . $_SESSION["email"];?>

</body>
</html>

Destroy a PHP Session

If you want to remove all session data, use session_unset() function for the corresponding key of the $_SESSION associative array, as given in the following example:

<?php // Starting session session_start();
 // Removing session data 
if(isset($_SESSION["firstname"]))
{ unset($_SESSION["email"]); } ?>

And now to see, to destroy a session completely, simply call the session_destroy() function. When we destroy a session , the session_destroy() function does not need any argument and a single call destroys all the session data.

<?php // Starting session 
session_start(); 
// Destroying session 
session_destroy(); ?>

In this tutorial, we will see how to store a minimum amount of data within the user’s browser itself using the PHP cookies.

What is a Cookie?

A cookie is a small text file that lets you store a small amount of information (nearly 4KB) on the user’s computer.

Each time with the same computer the browser requests a page to the server and all the information in the cookie is automatically sent to the server within the request.

And mostly cookie is frequently used to recognize the user. With the help of PHP, you can both create and retrieve cookie values.

How to set a Cookie in PHP

Through setcookie() function, we can create or set a cookie.

There are mostly all parameters are optional except the parameter of the name.
There are given below, all the parameters explanation of the phpsetcookie() function:

In this tutorial, we will see how to include one PHP file into another PHP file.

The PHP include() and PHP require() statement allow you to include the content of one PHP file into another PHP file. You can save your time and work using the PHP include() and PHP require() statements instead of typing the entire script multiple times.

With the help of PHP include() and PHP require() statement, we can utilize HTML code or PHP script code in many PHP script code. Let’s see the basic syntax of the PHP include() or PHP require() statement can be given listed below:

include("file path/filename"); Or include "file path/filename";
require("file path/filename"); Or require "file path/filename";

PHP include Examples

Example 1

Let’s suppose we have a standard menu php code file which is called “menu.php”:

<?php
echo '<a href="https://www.netzole.com/">Home</a> 
<a href="https://www.netzole.com/php-tutorial/">PHP Tutorial</a>
<a href="https://www.netzole.com/nodejs-tutorial/">Nodejs Tutorial
</a> 
<a href="https://www.netzole.com/python-tutorial/">Python Tutorial</a> 
?>

To include the menu file in a page, use the PHP include statement:

<html>
<body>

<div class="menu">
<?php include 'menu.php';?>
</div>
</br>
<h1>Welcome to home page!</h1>
<p>Some text.</p>
<p>Some more text.</p>

</body>
</html>

Example 2

Let’s suppose we have a standard footer php code file which is called “footer.php”:

<?php
echo "<p>Copyright &copy; 2017-" . date("Y") . " Netzole.com</p>";
?>

To include the menu and footer file in a page, use the PHP include statement:

<html>
<body>

<div class="menu">
<?php include 'menu.php';?>
</div>

<h1>Welcome to Netzole.com!</h1>
<p>Some text.</p>
<p>Some more text.</p>
<?php include 'footer.php';?>
</body>
</html>

PHP require

PHP require is used to similar to PHP include. Let’s see a PHP require example.

<html>
<body>

<div class="menu">
<?php require 'menu.php';?>
</div>
</br>
<h1>Welcome to home page!</h1>
<p>Some text.</p>
<p>Some more text.</p>

</body>
</html>

PHP include vs PHP require

• require will generate a fatal error (E_COMPILE_ERROR) and stop the script
• include will only generate a warning (E_WARNING) and the script will continue

At the top of, there is one big difference between PHP include and PHP require; when a file is included through the PHP include statement and PHP file cannot find it, the script will continue to execute: Let’s assume menu file(menu.php) does not exist.

<html>
<body>

<div class="menu">
<?php include 'menu.php';?>
</div>
</br>
<h1>Welcome to Netzole.com!</h1>
<p>Some text.</p>
<p>Some more text.</p>
<?php include 'footer.php';?>
</body>
</html>

On the other hand,If we given the same example using the PHP require statement, the echo statement will not be execute the script because the script execution dies after the PHP require statement returned a fatal error:

<html>
<body>

<div class="menu">
<h1> Home page Title!</h1>
<?php require 'menu.php';?>
</div>

<h2>Welcome to Netzole.com!</h2>
<p>Some text.</p>
<p>Some more text.</p>
<?php require 'footer.php';?>
</body>
</html>

In this tutorial we will see how to to upload files to the server.

Steps for Uploading PHP File Upload

PHP file upload features allows you to upload any kind of file like images, videos, ZIP files, Microsoft Office documents, PDFs, as well as executable files and a wide range of other file types.

Step 1: Creating an HTML form

<!DOCTYPE html>
<html>
<body>

<form action="uploadfile.php" method="post" enctype="multipart/form-data">
    Select image to upload:
    <input type="file" name="Upload_File" id="fileToUpload">
    <input type="submit" value="Upload Image" name="submit">
</form>

</body>
</html>

Follow these two rules for the HTML form above:
1. When we use to a file-select field the upload form must use method=”post”.
2. Always contain an enctype=”multipart/form-data” attribute.
The form which we created above sends data to a file called “uploadfile.php”, which we will create next.

Step 2: Create The Upload File PHP Script

The “uploadfile.php” file contains the following code for uploading a file:

<?php
  $folder_dir = "uploads/";
$folder_file = $target_dir . basename($_FILES["Upload_File"]["name"]);
$uploadfile = 1;
$imageFileType = strtolower(pathinfo($target_file,PATHINFO_EXTENSION));
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["Upload_File"]["tmp_name"]);
    if($check !== false) {
        echo "File is an image - " . $check["mime"] . ".";
        $uploadfile = 1;
    } else {
        echo "File is not an image.";
        $uploadfile = 0;
    }
}
?>

PHP code explained:

• $folder_dir = “uploads/” – specifies the directory where the file is going to be placed
• $folder_file specifies the path of the file to be uploaded
• $uploadfile=1 is not used yet (will be used later)
• $imageFileType holds the file extension of the file (in lower case)
• Next, check if the image file is an actual image or a fake image

Use move_uploaded_file() function for uploading files

This function used to moves the uploaded file to a new location. The move_uploaded_file() function checks first internally if the file is uploaded thorough the POST request. It moves the file if it is uploaded through the POST request.

<?php  
$folder_dir = "uploads/";
$folder_file = $target_path.basename( $_FILES['Upload_File']['name']);   
  
if(move_uploaded_file($_FILES['Upload_File']['tmp_name'], $target_path)) {  
    echo "File uploaded successfully!";  
} else{  
    echo "Sorry, file not uploaded, please try again!";  
}  
?>

In this PHP tutorial we will see how to format the date and time.

The PHP Date() Function

The PHP Date() function is used to formats a timestamp to a more readable date and time.
The computer stores dates and times in a format called UNIX Timestamp, which measures time as a number of seconds since the beginning of the Unix epoch (midnight Greenwich Mean Time on January 1, 1970 i.e. January 1, 1970 00:00:00 GMT ). For Example….See below:

<?php
   print time();
?>

Since this is not readable(1572854758) format for humans being to read, For humans convenient , PHP converts a timestamp to a format that is readable to humans and dates from your notation into a timestamp the computer understands. The syntax for the PHP date() function can be given below.

   date(format,timestamp)

There are two important facts generated which given below:
1. The format parameter in the date() function is required which is tell us to specifies the format of returned date and time.
2.Second think we can say timestamp is an optional parameter, if not included then current date and time will be used as a output. The following example clearer your all query which is displays today’s date:

<?php  
  
$today = date("d/m/Y");
echo $today;
  
?> 

Types of Parameters the Dates with PHP

There are some the date-related formatting characters that are commonly used in format string which given below and also see a example for batter understanding :

• d – Represent day of the month; (01 or 31)
• D – Represent day of the week in text as an abbreviation (Mon to Sun)
• m – Represent month in numbers with leading zeros (01 or 12)
• M – Represent month in text, abbreviated (Jan to Dec)
• y – Represent year in two digits (08 or 14)
• Y – Represent year in four digits (2008 or 2014)

The section of the date can be separated by putting other characters, like hyphens (-), dots (.), slashes (/), or spaces to add additional visual formatting.

<?php
echo "Today is " . date("Y/m/d") . "<br>";
echo "Today is " . date("Y.m.d") . "<br>";
echo "Today is " . date("Y-m-d") . "<br>";
echo "Today is " . date("l");
?>

Types of Parameters the Times with PHP

Similarly as a Date Formatting you can use the following characters to format the time string see below:

• h – Represent hour in 12-hour format with leading zeros (01 to 12)
• H – Represent hour in in 24-hour format with leading zeros (00 to 23)
• i – Represent minutes with leading zeros (00 to 59)
• s – Represent seconds with leading zeros (00 to 59)
• a – Represent lowercase ante meridiem and post meridiem (am or pm)
• A – Represent uppercase Ante meridiem and Post meridiem (AM or PM)

<?php
echo date("h:i:s") . "<br>";
echo date("F d, Y h:i:s A") . "<br>";
echo date("h:i a");
?>

The PHP time() Function

The PHP time() function is used to get the current time as a Unix timestamp. For example:

<?php
   print time();
?>

For humans convenient this output ,PHP converts a timestamp to a format that is readable to humans introduce date() function.

<?php
 $timestamp = 1572854758;
echo(date("F d, Y h:i:s", $timestamp));
?>

Loops are used to execute a block of statements, multiple times until and unless a specific condition is fulfilled. The basic idea behind a loop to helps the user to save both time and effort of repetitive tasks multiple times.
PHP supports four different types of loops.

1. The PHP for Loop

The for loop is used when user knows in advance how many times the block of code should run.

In PHP for loop, a loop variable is used to control the loop. First, initialize this loop variable to some value, then check whether this variable is less than or greater than the counter value.

If statement is true, then loop body is executed and loop variable gets updated . Steps are repeated till exit condition comes.

• Initialization Expression: In this expression we have to initialize the loop counter to some value. for example: $num = 0;
• Test Expression: In this expression we have to test the condition. If the condition evaluates to true then we will execute the body of loop and go to update expression otherwise we will exit from the for loop. For example: $num <= 7;
• Update Expression: After executing loop body this expression increments/decrements the loop variable by some value. for example: $num += 1;

<?php  
  
// code to illustrate for loop 
for ($x = 0; $x <= 7; $x++) { 
    echo "The number is: $x <br>"; 
}  
  
?> 

<?php  
  
// code to illustrate for loop 
for ($x = 1; ; $x++) {
    if ($x > 7) {
        break;
    }
   echo "The number is: $x <br>"; 
}
  
?> 

<?php  
  
$x = 1;
for (; ; ) {
    if ($x > 10) {
        break;
    }
   echo "The number is: $x <br>"; 
    $x++;
}
  
?> 

2. PHP foreach Loop

The PHP foreach Loop construct provides an easy way to iterate over arrays. foreach works only on arrays and objects and will create an error when you try to use it on a variable with a different data type.

<?php
$colors = array("red", "green", "blue", "yellow");

foreach ($colors as $value) {
    echo "$value <br>";
}
?>

The PHP while Loop

The while loop is very simple loop in PHP. The while loop executes a block of code as long as the specified condition is true.

<?php
$x = 1;

while($x <= 4) {
    echo "The number is: $x <br>";
    $x++;
}
?>

The switch case php is used to execute one of many blocks of code. The switch statement is similar to a series of IF statements on the same condition.

PHP Switch Case Statements

Syntax:

switch ($i) {
    case 0:
        echo "i equals 0";
        break;
    case 1:
        echo "i equals 1";
        break;
    case 2:
        echo "i equals 2";
        break;
}

Output:

<?php switch ($i) { case "apple": echo "i is apple"; break; case "bar": echo "i is bar"; break; case "cake": echo "i is cake"; break; } ?>

In this PHP tutorial, today we learn PHP If else Condition with the help of examples.

PHP Conditional statements are used to perform different actions based on the results of a logical or comparative test conditions at run time

PHP Conditional Statements

There are many statements in PHP that you can use to perform different actions which is given below:

• The if statement
• The if…else statement
• The if…elseif….else statement
• The switch…case statement

Now Let’s start to explain each of these conditions statements see below:

PHP – The if Statement

The if statement is used to execute some code only if the condition is true.

Syntax:

Flowchart:

<?php  
$num=50;  
if($num<60){  
echo "$num is less than 60";  
}  
?>  

Output:

PHP – The if…else Statement

The if…else statement executes some code if a condition is true and another block of code if it is false.

Syntax:

<?php  
$num=12;  
if($num%2==0){  
echo "$num is even number";  
}else{  
echo "$num is odd number";  
}  
?>  

Output:

PHP – The if…elseif…else Statement

The if…elseif…else a special statement that is used to more than two conditions.

Syntax:

<?php  
$d = date("D");
if($d == "Sat"){
    echo "Have a nice weekend!";
} elseif($d == "Sun"){
    echo "Have a nice Sunday!";
} else{
    echo "Have a nice day!";
}
?>  

Output:

Will will explain about PHP switch-case statement in the next chapter.

An array is a data structure that holds multiple values in one single variable at a time.

Let’s see you have a multiple items (a list of fruit names, for example), storing the fruit in single variables could look like this:

Now if you want to loop through the fruits and find a specific one? And what if you had lots of fruit ?
The solution is to create an array for this problem!. Let’s starts with how to create an array?.
In PHP, the array() function is used to create an array:

Types Of Array

There are three types of array in PHP which is given below and describing array one by one:

• Indexed array — An array with a numeric element.
• Associative array — An array where each element has its own specific value.
• Multidimensional array — An array containing one or more arrays within itself.

Indexed array

An indexed or numeric array holds each array value with a numeric index. There are two ways of creating an indexed array.
a. Simple Way: The index can be assigned automatically (index always starts at 0) .For an example see given below:

<?php
// Define an indexed array
$fruits= array("Apple", "Orange", "Papaya");
?>

b. Indexes are Assigned Manually Way:

<?php
$fruits[0] = "Apple"; 
$fruits[1] = "Orange"; 
$fruits[2] = "Papaya"; 
?>

Associative array
