Generally, a PHP file contains HTML tags and some PHP scripting code. It’s easy to create a simple PHP example. Just create a file, write HTML tags + PHP code, and save it with a .php extension. 💻
Note: PHP statements end with a semicolon (;).
All PHP code goes between the PHP tag: <?php (start) and ?> (end).
PHP Tag Syntax:
<?php
// your code here
?>
Example: Simple PHP Program 👨💻
File: first.php
<!DOCTYPE html>
<html>
<body>
<?php
echo "<h2>Hello First PHP</h2>";
?>
</body>
</html>
Output:
Hello First PHP
How to run PHP programs in XAMPP ⚙️
PHP is a popular backend programming language. You can write PHP programs in any text editor like Notepad, Notepad++, Dreamweaver, etc., and save them with a .php extension (e.g., filename.php) inside the htdocs folder in XAMPP.
For example: p1.php.
Directory Example:
If you’re using Windows and have XAMPP installed on your D drive, the path for the htdocs directory will be:
D:\xampp\htdocs.
PHP programs run in a web browser like Chrome, Internet Explorer, Firefox, etc. Below are the steps to run a PHP program.
Steps to Run PHP Code in XAMPP:
Step 1: Create a Simple PHP Program like “Hello World!”
<?php
echo "Hello World!";
?>
Step 2: Save the file as hello.php in the htdocs folder (inside the XAMPP folder).
Note: Make sure the PHP program is saved in the htdocs folder; otherwise, you’ll get an error: Object Not Found.
Step 3: Run the XAMPP Server 🚀 and start Apache and MySQL.
Step 4: Open the web browser and type http://localhost/hello.php in the browser window.
Step 5: The output will display as:
Hello World!
Running PHP Code in XAMPP 🖥️
Most of the time, PHP programs run as a web server module. However, PHP can also be executed via the Command Line Interface (CLI).
PHP Case Sensitivity 🔠
In PHP:
- Keywords (e.g.,
echo,if,else,while), functions, and user-defined functions are NOT case-sensitive. - Variable names are case-sensitive.
Example 1: Case-Insensitive Keywords and Functions:
<!DOCTYPE html>
<html>
<body>
<?php
echo "Hello world using echo </br>";
ECHO "Hello world using ECHO </br>";
EcHo "Hello world using EcHo </br>";
?>
</body>
</html>
Output:
Hello world using echo
Hello world using ECHO
Hello world using EcHo
Example 2: Case-Sensitive Variables:
<html>
<body>
<?php
$color = "black";
echo "My car is ". $ColoR ."</br>";
echo "My dog is ". $color ."</br>";
echo "My Phone is ". $COLOR ."</br>";
?>
</body>
</html>
Output:
Notice: Undefined variable: ColoR in D:\xampp\htdocs\program\p2.php on line 8
My car is
My dog is black
Notice: Undefined variable: COLOR in D:\xampp\htdocs\program\p2.php on line 10
My Phone is
Only the $color variable printed its value, while $ColoR and $COLOR were treated as undefined variables. 🚨
That’s it! Now you’re ready to create and run PHP code in XAMPP! 😎
