PHP 二维数组排序

php对二维数组的排序其实很简单，但要是不知道array_multisort这个函数就比较费事了。

$data = array(); 
$data[] = array('volume' => 67, 'edition' => 2); 
$data[] = array('volume' => 86, 'edition' => 1); 
$data[] = array('volume' => 85, 'edition' => 6); 
$data[] = array('volume' => 98, 'edition' => 2); 
$data[] = array('volume' => 86, 'edition' => 6); 
$data[] = array('volume' => 67, 'edition' => 7); 
 
// 取得列的列表 
foreach ($data as $key => $row) 
{ 
    $volume[$key]  = $row['volume']; 
    $edition[$key] = $row['edition']; 
} 
 
//当然你也可以填写一个值进行排序  如：array_multisort($volume, SORT_DESC, $data); 

array_multisort($volume, SORT_DESC, $edition, SORT_ASC, $data); print_r($data);
