I have an array with some values

Array ( [0] => MSC-00107.mp4 [1] => SPTWLL-00108.mp4 [2] => FSHNWLL-00109.mp4)

So I want to remove elements contains a part of string

$remove = 'WLL';

So if an element contains the string set in $remove I want remove from array If I use in_array it will remove only if the string is equal

if (in_array($remove, $array)) 
{
    unset($array[array_search($remove,$array)]);
}

and it doesn't work. Can you help me? thanks

You can filter array, fiddle:

$array = array_filter($array, function($value) use ($remove) {
    return false === strpos($value, $remove);
});

You could return elements that don't match:

$array = preg_grep("/$remove/i", $array, PREG_GREP_INVERT);

My example just loops through all the elements of the array removing the items containing a given string:

https://onlinephp.io/c/275f4

$array = ['test', 'test123', '456test', 'anotherone'];
removeItemsFromArrayMatching($array, 'test');
var_dump($array);

function removeItemsFromArrayMatching(&$array, $remove){
    $i = 0;
    foreach($array as &$item) 
    {
        if( str_contains($item, $remove) )
            unset($array[$i]);
        $i  ;
    }
    $array = array_values($array);
}

You can use strpos() which will show you whether to string contains another phrase or not. You need to use it with foreach

foreach($array as $key){
if (strpos( $key, $remove ) !== FALSE ){
    unset($array[array_search($remove,$array)]);
     }
}
