Yet another associative array test:
<?php
function binary_nand ($a, $b) { return !$a && !$b; }
function binary_nor ($a, $b) { return !$a || !$b; }
// Returns true if array has elements with non-numeric keys
function is_associative_array ($arr) {
return is_array($arr) && !empty($arr) &&
array_reduce(array_map("is_numeric", array_keys($arr)), "binary_nor", true);
}
// Returns true if all elements of array have a non-numeric key
function is_strict_associative_array ($arr) {
return is_array($arr) && !empty($arr) &&
array_reduce(array_map("is_numeric", array_keys($arr)), "binary_nand", false);
