Thanks sasa I'll try it out

The replacement would come from the array of which the key matched (randomly). for example if the multi-array is: array("chocolate", "cinnamon", "strudels"); and the thing being compared is "chocolate" then "chocolate" could be replaced with "cinnamon", "strudels", or "chocolate"

Certainly, I have a multi-dimensional array and a normal array. I want to loop threw the array and if the normal array has any elements that are equal to any elements of the multi-dimensional array, then replace it with a random element of the sub array of the multi-dimensional array. I hope that clarifies a few things.

Hello, here is the PHP situation I'm in. I'll type it out in pseudo-ish code first. <?php $multi_array = array( array("cats", "dogs", "sheep", "walruses"), array("jazz", "larva", "pencils", "derp"), array("to", "much") ); $string = array("the", "cats", "ate", "too", "many", "pencils"); $count = count($string); for($i = 0; $i < $count; ++$i) { if($string[$i] IN ARRAY $multi_array) { THEN replace $string[$i] with a random word in the sub array of the multi-array for example, if $string[$i] is cat, then it would replace it with any of the words in the sub array of multi-array, so it could be "cats", "dogs", "sheep", or "walruses" } } ?> I have no idea how to do this and tried thinking of ways for an hour and a half.
