in_array() does not seem to check after key 2

Question

I have a simple function that should just give me TRUE or FALSE if a value is find in an array.

function bypass($user, $bypassUsers){
    $users = explode(",", $bypassUsers);
    // trim($users);

    if(in_array($user,$users)){
        return true;
    } else {
        return false;
    }
}

While to me everything looks of when I have more than 2 values in the array, the function returns FALSE as if in_array() does not see from key [2].

Any idea?

Answer 1

If you want to apply trim to all elements, instead of:

$users = explode(",", $bypassUsers);
trim($users);

You should do this instead:

$users = array_map('trim', explode(',', $bypassUsers));

It applies trim() to the result of explode() . Afterwards, you can return the result in one statement:

return in_array($user, $users, true); 
// third argument determines whether to use == or === for comparison

Answer 2

function bypass($user, $bypassUsers){
    $users = explode(",", $bypassUsers);
    foreach($users as $key=>$usr){
        $users[$key] = trim($usr);
    }

    if(in_array(trim($user),$users)){
        return true;
    } else {
        return false;
    }
}

Trim is the problem because it works with string not with an array
