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:
<?php
function array_sanitize($array, $filterName) {
$negFilter = create_function('$arg', 'return !'.$filterName.'($arg);');
return array_filter($array, $negFilter);
}
//Example:
$a = array('a'=>6,'b'=>1,'c'=>4,'d'=>9);
function isOdd($arg) { return $arg % 2 == 1; }
print_r (array_sanitize($a, 'isOdd')); // outputs 'Array ( [a] => 6
