Note Submitter: Lea Hayes ---- Determine whether an object field matches needle. Usage Example: --------------- $arr = array( new stdClass(), new stdClass() ); $arr[0]->colour = 'red'; $arr[1]->colour = 'green'; $arr[1]->state = 'enabled'; if (in_array_field('red', 'colour', $arr)) echo 'Item exists with colour red.'; if (in_array_field('magenta', 'colour', $arr)) echo 'Item exists with colour magenta.'; if (in_array_field('enabled', 'state', $arr)) echo 'Item exists with enabled state.'; Output: -------- Item exists with colour red. Item exists with enabled state. function in_array_field($needle, $needle_field, $haystack, $strict = false) { if ($strict) { foreach ($haystack as $item) if (isset($item->$needle_field) && $item->$needle_field === $needle) return true; } else { foreach ($haystack as $item) if (isset($item->$needle_field) && $item->$needle_field == $needle) return true; } return false; }
