a rewrite of alex at alexelectronics dot com's code, with the strict option added and some
slight improvements in speed and readability:
<?php
function in_multi_array ($needle, $haystack, $strict) {
if ($strict) {
foreach ($haystack as $item) {
if (is_array ($item)) {
if (in_multi_array ($needle, $item, $strict)) {
return true;
}
} else {
if ($needle === $item) {
return true;
}
}
}
} else {
foreach ($haystack as $item) {
if (is_array ($item)) {
if (in_multi_array ($needle, $item, $strict)) {
return true;
}
} else {
if ($needle == $item) {
return true;
}
}
}
}
return false;
}
?>
