Sorting an Array by Values in PHP
How To Sort an Array by Values in PHP?
✍: FYIcenter.com
Sorting an array by values is doable by using the sort() function. It will re-order all pairs of keys and values based on the alphanumeric order of the values. Then it will replace all keys with integer keys sequentially starting with 0. So using sort() on arrays with integer keys (traditional index based array) is safe. It is un-safe to use sort() on arrays with string keys (maps). Be careful. Here is a PHP script on how to use sort():
<?php $mixed = array(); $mixed["Zero"] = "PHP"; $mixed[1] = "Perl"; $mixed["Two"] = "Java"; $mixed["3"] = "C+"; $mixed[""] = "Basic"; $mixed[] = "Pascal"; $mixed[] = "FORTRAN"; sort($mixed); print("Sorted by values:\n"); print_r($mixed); ?>
This script will print:
Sorted by values: Array ( [0] => Basic [1] => C+ [2] => FORTRAN [3] => Java [4] => PHP [5] => Pascal [6] => Perl )
