why does this happen

[Talguy]

every time i run my script i recieve an error saying that when i call implode that I have bad arguments for it. below is the section from my script where i am calling implode.

// Pop off the last folder name and join the the just back together with a '/'
$tempPath = explode('/', $oldPath);
$tempPathArray = array_pop($tempPath);
$newPath = implode("/", $tempPathArray);

what I am trying to do is get the path of a folder and navigate to its parent folder by exploding the path popping off the end and joining it all back together with implode but i get the bad argument error all the time even though the script works. is it that i just need to put a @ in front of it because the error will come up no matter what.

array_pop() returns a scalar value (the last element of the array), not an array. You could do...

$tempPath = explode('/', $oldPath);
$subDir = array_pop($tempPath);
$newPath = implode("/", $tempPath);

thats right i know what I did. I was setting it to implode the last element from the array with a '/' where it was given me the array bc i was passing a string into the function instead of an array.
Thanks for the help what a stupid mistake that was.
