how to differ 0 from FALSE when using in_array

Question

i have a function to filter unwanted values in array (usually false and empty values) here it is :

function filter_array($arr ,  $filter = array('' , FALSE)){

    foreach($arr as $k=>$v)
    {
        if(in_array(trim($v) , $filter)) 
        unset($arr[$k]);
    }

    return $arr;
}

here is the problem , it considering 0 as false and removing them from array ... how can i fix this ?

one way is to loop trough $filter and and use === to check the values but i want to avoid another loop

Read the manual. Strict comparison is in the third argument. — Antony

in_array takes a third optional argument for strict comparison.

in_array(trim($v) , $filter, true)
