从条件中删除关联数组中的特定键

Question

I ran into a coding situation where i'd prefer to keep a certain condition as compact as possible:

// $data and $control are arrays
if($data==$control || ($someBool && $data==$control))
    return $c;

Of course this condition makes no sense that way. My goal is to remove a key from $control in the last part of my condition, before comparing it against $data.

Of course it could be done like this:

function chopByKey(array $arr, $key){
    if(!isset($arr[$key]))
        return $arr;
    unset($arr[$key]);
    return $arr;
}

And rewrite the condition:

if($data==$control || ($someBool && $data==chopByKey($control, 'someKey') ))
    return $c;

Please note

I am looking for a solution that i can use within my condition, not any solution that requires any additional step ahead of the condition or the definition of a custom function, be it anonymous or not.

My question is

Is there any more elegant way to do this, without defining a new custom function?

If yes, how?

Answer 1

I came up with the following line:

$control = array('hello' => 'world', 'foo' => 'bar');
$data = array('hello' => 'world');
$someBool = true;

if ($data == $control || $someBool && $data == array_diff_key($control, array('foo' => 0))) {

Side effect is that $control is not modified by the condition.
