# php數組函數 -- array\_column,array\_multisort 實現二維數組排序 ~~~ $a = array( array( 'id' => 5698, 'key' => 'Bill', 'value' => '1', ), array( 'id' => 4767, 'key' => 'Steve', 'value' => '0', ), array( 'id' => 3809, 'key' => 'Mark', 'value' => '2', ) ); // 看第一張圖 $values = array_column($a,'value'); //按照某個字段對二維數組排序 array_multisort($values,SORT_DESC,$a); print_r($a);exit; ~~~ ### 輸出： ``` Array ( [0] => Array ( [id] => 3809 [key] => Mark [value] => 2 ) [1] => Array ( [id] => 5698 [key] => Bill [value] => 1 ) [2] => Array ( [id] => 4767 [key] => Steve [value] => 0 ) ) ```
