PHP Array Delete

Can PHP really be missing a way of deleting items from an array based on the key? Seems so, so here am am just sharing a snippet of code that lets you do just that.

This function will work with any number of array keys and does some clever shunting around with the array_flip and array_slice functions.

// utility to remove array items from the key
function array_remove_key() {
   $args = func_get_args();
   return array_diff_key($args[0],array_flip(array_slice($args,1)));

// usage...
$new_array = array_remove_key($arrayvar, "key1", "key2", "key3");
