How do I avoid error - Strict Standards: Only variables should be passed by reference

Question

I am recieving the following error

Strict Standards: Only variables should be passed by reference in C:\wamp\www\dragdrop\newhotel\reservation\ajax\tips.php on line 8

Line 8 is

$img=mysql_real_escape_string(end(explode('/',$_POST['img'])));

I'm a newbie please help me..

I think [basename](http://php.net/basename) would suit you better — Touki, Mar 11 '13 at 10:55

Explode is a function so you can't pass it to end. Use an intermediate variable.

$List = explode('/',$_POST['img']);
$img=mysql_real_escape_string(end($List));

Should work

You are not passing a variable, you are passing an array directly.

$var = explode('/',$_POST['img']);
$var = end($var);
$img = mysql_real_escape_string($var);
