Note Submitter: mike at van dot lammeren dot net ---- I started this thread in 2003, when I posted as 'mike-php'. There have been a lot of suggestions of questionable quality since then. You may be interested to know that all this time later, I still use the 'vhermecz' version of my original algorithm. /** * Note: * - empty arrays are identified as associative arrays. * - associative arrays whose keys are coincidentally the same as a non-associative array * will be identified as NOT associative * @param array $given * @return boolean true if the given value is an associative array, false otherwise */ function is_assoc_array($given) { return is_array($given) and array_keys($given) !== range(0, sizeof($given)-1); }
