If you want to search for a value only in one column of all entries in a multidimensional array,
here's a function that will do that for you. It returns a one-dimensional array containing the
numerical index of each entry matched. (apologies for the horrible formatting -- this comment system
sucks)
function array_search_column($needle, $haystack, $column) {
$matches = array();
foreach($haystack as $foo) {
if($foo[$column] == $needle)
array_push($matches, $i);
$i++;
}
return $matches;
}
