How do I solve a "Wrong datatype" error in my PHP script?

Question

Full Error:

in_array() [<a href='function.in-array'>function.in-array</a>]: Wrong datatype for second argument in /var/www/vhosts/example.com/httpdocs/sites/example.com/themes/example/page.tpl.php on line 22.

Relevant Code:

if (($_GET['nid']) && ($_GET['uid'] != '5')) :
    $arr = array("7916","7917","7996","7918","7990","7919","7921","7924","7925","7923","7922","8011");
    reset($arr);
    $nid = $_GET['nid'];
    // settype($nid, "integer"); 
elseif(($_GET['uid'] == '5') && ($is_front)):
    include("include_ad_front.php");    
endif;

if((in_array($nid, $arr)) && ($is_front) && (!$_GET['uid'])) {
    //code continues below...

Lines 3 and 5 were just my attemts to fix the problem. Line 10 is actually line 22 in this error and the one throwing the error.

I think I see your problem.

You have the in_array stuff being called after you've done your first set of if..else checks. Now the first part of your if...else has the array being created, but not the second.

Try moving the array somewhere before your first if...else instead of inside it.

It should't create the array unless that first issue validates, but I see what you're saying... Let me look at it and see if I get it. Just to test though, I'll try your suggestion as a band aid.

If you only want to check the array if the first if validates, try checking the existence of the $arr variable, for example if (isset($arr) and isset($nid) and in_array($nid, $arr) ...) {
