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.
