Question

I have a PHP array with a parent called “items.” In that array, I want to remove all values that do not contain a string (which I’m gonna use regex to find). How would I do this?

Answer 1

foreach($array['items'] as $key=>$value) { // loop through the array
    if( !preg_match("/your_regex/", $value) ) {
        unset($array['items'][$key]);
    }
}
