PHP syntax: sort an associative array by value with asort

Posted December 28, 2003 by Quinn McHenry in PHP programming

To sort an associative array by the array values, use asort.


An optional parameter (sort_flags) can be passed to asort to alter the way that it sorts the array. The following code will sort an associative array numerically by array value.

asort($ar, SORT_NUMERIC);

Without this option, the index values ’15, 2, 1′ would be sorted ‘1, 15, 2’ and with the SORT_NUMERIC option, the values would be sorted 1, 2, 15.
