How to get current filename as variable ?

Sometimes you need just the filename of the current script, without the path. This snippet does just that using the SCRIPT_NAME and explode function.

<?php
    $currentFile = $_SERVER["SCRIPT_NAME"];
    $parts = Explode('/', $currentFile);
    $currentFile = $parts[count($parts) - 1];
?>

Getting the Current Filename as a Variable
Here's how to retrieve the current filename in your script:

• Understanding the Environment Variable: PHP offers a built-in environment variable called `$_SERVER['SCRIPT_NAME']`. This variable stores the path of the currently executing script relative to the document root.
• Utilizing the `explode` Function: The `explode` function in PHP breaks a string into an array of substrings based on a delimiter. In this context, we use the delimiter "/" to separate the path components.
• Extracting the Filename: After splitting the path, the last element of the resulting array represents the filename.
