Mike's function is quite cool, it is just the one, I was searching for. Using range is a great
idea! But it's a bit long for me. Here is a shorter version:
<?php
function is_assoc_array($var) {
if (!is_array($var)) {
return false;
}
return array_keys($var)!==range(0,sizeof($var)-1);
}
?>
Or, if you don't want to type that much:
<?php
function is_assoc($var) {
return is_array($var) && array_keys($var)!==range(0,sizeof($var)-1);
}
?>
