Remove value from array based on value?

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?

You can try using array_filter.

$items = array(
    #some values
);
$regex= '/^[some]+(regex)*$/i';
$items = array_filter($items, function($a) use ($regex){
    return preg_match($regex, $a) !== 0;
});

NOTE: This only works in PHP 5.3+. In 5.2, you can do it this way:

function checkStr($a){
    $regex= '/^[some]+(regex)*$/i';
    return preg_match($regex, $a) !== 0;
}

$items = array(
    #some values
);
$items = array_filter($items, 'checkStr');

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