Using in_array in a loop

[mattastic]

Hello,

I'm trying to loop through an existing array and testing to see if the index is in another array.

It breaks after the number 2 in $tester.

can anyone help? Thanks in advance

$tester =array(5,10,11,8,5,6,2,0,1);

// search for max array key in existing array
$key = max(array_keys($data['_navKnowledgebaseCategoryContainer']));

// loop through array

for ($i = 0; $i <= $key; $i++) {

if (isset($data['_navKnowledgebaseCategoryContainer'][$i])){

// if articles exist and index is in $tester then show stuff

	if(($data['_navKnowledgebaseCategoryContainer'][$i]['totalarticles'] > 0) && (in_array($i, $tester))){ 

	echo "stuff";                    

     }

}

}

Maybe it so happens that $key == 2. From what I see, the in_array call for "testing to see if the index is in another array" is correct. The mistake probably lies in the input, in the logic that you did not explain, or elsewhere.
