note 45283 deleted from function.array-multisort by aidan

Note Submitter: jon at PLEASENOSPAMMY dot webtrick dot com ---- I had trouble understanding this function, and had trouble getting the array sorted by multiple columns (like ORDER BY last_name, first_name). What I finally figured out is that each ORDER BY parameter gets its own array. So below, $sortarr1 is a list of last names, and $sortarr2 is a list of first names. I hope this helps somebody! <? function sortMultiArray($marray, $column,$column2='') { //use the existing array to build the sorting array(s) foreach ($marray as $row) { $sortarr1[] = $row[$column]; if ($column2) $sortarr2[] = $row[$column2]; } //$sortarr1 has all the last names, //$sortarr2, has all the first names // the first two arrays are used to sort the last array array_multisort($sortarr1,$sortarr2, $marray); return $marray; } //calling the function sortMultiArray($anArray,'last_name','first_name'); ?>
