Remove keys without specified names

I have an array like this:

Array
(
    [44] => 2
    [21] => 2
    [] => 2
    [27] => 2
)

How to find and remove (unset) keys without specified names? So in this case array should look like this:

Array
(
    [44] => 2
    [21] => 2
    [27] => 2
)
Solution

  • could be the key is '' (empty string)

    in this case assuming you have 

       $myArray = [
    [44] => 2,
    []   => 2,
    [21] => 2,
    [27] => 2,
   ]

    then try unset 

     unset($myArray['']);
