I have an associative array of data and I have an array of keys I would like to remove from that array (while keeping the remaining keys in original order -- not that this is likely to be a constraint).
I am looking for a one liner of php to do this.
I already know how I could loop through the arrays but it seems there should be some array_map with unset or array_filter solution just outside of my grasp.
I have searched around for a bit but found nothing too concise.
To be clear this is the problem to do in one line:
//have this example associative array of data
$data = array(
'blue' => 43,
'red' => 87,
'purple' => 130,
'green' => 12,
'yellow' => 31
);
//and this array of keys to remove
$bad_keys = array(
'purple',
'yellow'
);
//some one liner here and then $data will only have the keys blue, red, green
$out = array_diff_key($data, array_flip($bad_keys));
All I did was look through the list of Array functions until I found the one I needed (_diff_key).
