Variable reference error in PHP

Question

I have upgraded PHP from v5.3 to v5.4 and I am now getting the following error:

Strict standards: Only variables should be passed by reference

Code:

$filename = array_pop(explode("/", $_SERVER['SCRIPT_FILENAME']));

How to fix this?

try `$filename_arr = explode("/", $_SERVER['SCRIPT_FILENAME']); $filename = array_pop($filename_arr);` — air4x, Sep 23 '12 at 14:47
`array_pop` expects a variable as it tries to remove the last item from it. — Gumbo, Sep 23 '12 at 14:48

Breaking the code apart would resolve the error

$filename = explode("/", $_SERVER['SCRIPT_FILENAME']);
$filename = array_pop($filename);

echo $filename ;
