You can use a recursive function.

function in_array_recursive($needle, $haystack) {
    foreach ($haystack as $value) {
        if ($needle == $value) return true;  
        if (is_array($value) && in_array_recursive($needle, $value)) return true;
    }
    return false;
}

$found = in_array_recursive('Engraving', $your_array);

The above function will only match entire values. If you need to match parts of strings, you will need to add a strpos check (Thanks, AbraCadaver) .

function in_array_recursive($needle, $haystack) {
    foreach ($haystack as $value) {
        if (is_array($value)) {
            if (in_array_recursive($needle, $value)) return true;
        } else {
            if (strpos($value, $needle) !== false) return true;  
        }
    }
    return false;
}

$found = in_array_recursive('Engraving', $your_array);
