Extracting the Filename Without Extension in PHP

Getting the filename of the currently executed script in PHP is easy with the magic constant __FILE__. However, if you need to extract the filename without its extension, such as the ".php" suffix, the process is slightly different.

The basename() Solution:

To remove the extension using the basename() function, you can:

basename(__FILE__, '.php');

This will return the filename without the .php extension, such as "jquery.js" for the string "jquery.js.php".

A Generic Extension Remover:

For a more versatile solution that can handle any file extension, you can define a custom function:

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

Using this function:

var_dump(chopExtension('bob.php')); // "bob"
var_dump(chopExtension('bob.i.have.dots.zip')); // "bob.i.have.dots"

Standard String Functions:

Finally, you can use standard string functions for a quicker approach:

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