PHP two-dimensional array sorting simple implementation method, php two-dimensional array sorting

This article describes how to sort two-dimensional arrays in PHP. We will share this with you for your reference. The details are as follows:

Function multi_compare ($ a, $ B) {$ val_arr = array ('gold' => 'asc ', 'Silver '=> 'desc' // You can also add additional sorting conditions); foreach ($ val_arr as $ key => $ val) {if ($ a [$ key] = $ B [$ key]) {continue;} return ($ val = 'desc ')? -1:1) * ($ a [$ key] <$ B [$ key])? -1: 1);} return 0;} $ arr = array ('gold' => 1, 'Silver '=> 2 ), array ('gold' => 8, 'Silver '=> 10), array ('gold' => 8, 'Silver' => 8 ), array ('gold' => 2, 'Silver '=> 1),); uasort ($ arr, 'Multi _ compare'); print_r ($ arr );

The running result is as follows:

Array ([0] => Array ([gold] => 1 [silver] => 2) [3] => Array ([gold] => 2 [silver] => 1) [1] => Array ([gold] => 8 [silver] => 10) [2] => Array ([gold] => 8 [silver] => 8 ))
