Note Submitter: grigory ---- Another version of function is_assoc_array(). It is not short, but seems to be quite effective. Main idea: when 'foreach' works on a list - it uses numbers as keys, and that keys are numbers, start with 0, and in sequenced order. Anything another - and array is not a list. <?php function is_assoc_array( $obj ) { if( ! is_array( $obj ) ) return false; $islist = true; foreach( $obj as $key => $val ) { if( gettype( $key ) == 'string' ) return true; if( isset( $prev_key ) && $key !== 0 ) { if( $key != $prev_key + 1 ) return true; } $prev_key = $key; } return false; } ?>
