I just ran across a simple problem I couldn't solve, namely to create a
function that does the opposite of array_filter, call it array_sanitize.
The closest I could come doesn't work for anonymous functions:
Would this do the job?
function array_sanitize($array,$filterName)
{
return array_diff($array,array_filter($array,$filterName));
}
Seems to work in my testing:
$a = array('a'=>6,'b'=>1,'c'=>4,'d'=>9);
$isOdd = create_function('$arg','return $arg % 2 == 1;');
print_r(array_sanitize($a, $isOdd));
