Strict Standards: Only variables should be passed by reference in

Question

I am trying to work on a forgot password system. I have no clue why I am getting this error, I've rechecked the code almost five times. Any help would be wonderful.

by the way, this is Exception.

Error- Strict Standards: Only variables should be passed by reference in C:\xampp\htdocs\core\init.php on line 8

recover.php

echo $current_file = end(explode('/', $_SERVER['SCRIPT_NAME']));

It's telling you the problem. It sounds like your passing something other than a variable by reference. Then, it tells you `line 8` of `recover.php`. — ChiefTwoPencils, Aug 05 '12 at 06:21

This error seems to be because you are passing in a value to explode() rather than a variable, try this:

$var = $_SERVER['SCRIPT_NAME'];
$current_file = end(explode('/', $var));

sorry, that didn't help at all. I've still got the error, thanks though. – user1577002 Aug 05 '12 at 06:29

It’s `end` that expects a reference as it changes the internal array value pointer. – Gumbo Aug 05 '12 at 06:32
Gumbo is right. Explode the thing into a variable and then send the variable to end. – Ivan Pintar Aug 05 '12 at 06:35

As explained very well here, the PHP end() method waits for a variable reference to work correctly. What you have to do is simply give a variable reference instead of a plain value.

$var = $_SERVER['SCRIPT_NAME'];
$exploded = explode('/', $var);
$current_file = end($exploded);
