How to Extract a Script Filename Without its PHP Extension?

Extracting Script Filename Without PHP Extension

Getting the full script filename, including its extension, can be easily accomplished using PHP's magic constant __FILE__. However, if your goal is to obtain the filename without the ".php" extension, you need a slightly different approach.

Method 1: Using basename() with FILE

The basename() function can remove the extension from __FILE__. For example:

$filenameWithoutExtension = basename(__FILE__, '.php');

This will assign "jquery.js" to $filenameWithoutExtension for the given script name "jquery.js.php".

Method 2: Generic Extension Remover Function

You can also create a generic function that removes the extension from any filename:

function chopExtension($filename) {
    return pathinfo($filename, PATHINFO_FILENAME);
}

Method 3: Substring and String Splitting

Another option is to use standard string library functions, like substr() and strrpos():

function chopExtension($filename) {
    return substr($filename, 0, strrpos($filename, '.'));
}

Performance Considerations

Benchmarking shows that using string functions is much faster than using pathinfo().

Example Usage

$filenameWithoutExtension = chopExtension('bob.php'); // "bob"
$filenameWithoutExtension2 = chopExtension('bob.i.have.dots.zip'); // "bob.i.have.dots"
