PHP Remove elements from associative array

Question

I have an PHP array that looks something like this:

Index              Key     Value
[0]                1       Awaiting for Confirmation
[1]                        


        

Answer 1

$key = array_search("Mark As Spam", $array);
unset($array[$key]);

For 2D arrays...

$remove = array("Mark As Spam", "Completed");
foreach($arrays as $array){
    foreach($array as $key => $value){
        if(in_array($value, $remove)) unset($array[$key]);
    }
}
