Get the current script file name – Dev

The best answers to the question “Get the current script file name” in the category Dev.


If I have PHP script, how can I get the filename from inside that script?

Also, given the name of a script of the form jquery.js.php, how can I extract just the “jquery.js” part?


When you want your include to know what file it is in (ie. what script name was actually requested), use:

basename($_SERVER["SCRIPT_FILENAME"], '.php')

Because when you are writing to a file you usually know its name.

Edit: As noted by Alec Teal, if you use symlinks it will show the symlink name instead.


Just use the PHP magic constant __FILE__ to get the current filename.

But it seems you want the part without .php. So…

basename(__FILE__, '.php'); 

A more generic file extension remover would look like this…

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

var_dump(chopExtension('bob.php')); // string(3) "bob"
var_dump(chopExtension('')); // string(15) "bob.i.have.dots"

Using standard string library functions is much quicker, as you’d expect.

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


Here is the difference between basename(__FILE__, ".php") and basename($_SERVER['REQUEST_URI'], ".php").

basename(__FILE__, ".php") shows the name of the file where this code is included – It means that if you include this code in header.php and current page is index.php, it will return header not index.

basename($_SERVER["REQUEST_URI"], ".php") – If you use include this code in header.php and current page is index.php, it will return index not header.
