PHP Functions

Functions in PHP are blocks of code that can be reused. They allow you to encapsulate functionality and make your code more modular and maintainable.

Syntax

function functionName() {
    // code to be executed
}

Example of PHP Function

<?php
function greet($name) {
    return "Hello, " . $name . "!";
}

echo greet("World");
?>

Output:

Hello, World!

Explanation: This example demonstrates how to define and call a function in PHP. The function greet takes a parameter $name and returns a greeting message.
