How to Remove the Extension from a Filename in PHP?

Extracting Filename without Extension in PHP

To obtain the filename of the currently executed PHP script without its ".php" extension, you can utilize the PHP magic constant __FILE__. However, it appears that you require the filename without the extension.

Solution 1: Using basename()

To accomplish this, you can employ the basename() function:

basename(__FILE__, '.php');

For instance, provided the script filename "jquery.js.php," this code would output "jquery.js."

Solution 2: Generic Extension Remover Function

A more versatile solution would be to create a function that strips the extension from any filename irrespective of its type:

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

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

Solution 3: Using String Library Functions

For enhanced speed, you can opt for standard string library functions:

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