Assuming your outer array is called $array_of_arrays: <?php $found = 0; foreach ($array_of_arrays as $array) { if ($array['alias'] == 'foo') { $found = 1; break; } } if ($found) { // you found it! } else { // too bad! } ?> Or, you can look at this: http://www.php.net/manual/en/function.in-array.php if you're not sure what key 'foo' will be at, or this: http://www.php.net/manual/en/function.array-search.php if you're not sure what key 'foo' will be at and you want to know what that key is.
