一个简单的php 二维数组按第二维 里面的元素进行排序这样不影响数据,只对数组里面的内容进行排序一下,有需要的朋友参考一下。

 代码如下 复制代码
 
$ar = array(
    0 => array('a'=>5, 'b'=>3, 'c'=>3),
    1 => array('a'=>5, 'b'=>2, 'c'=>1),
    2 => array('a'=>1, 'b'=>1, 'c'=>2)
);
$a = array();
$b = array();
 
 
foreach($ar as $k=>$v) {
  $a[$k] = $v['a'];
  //$b[$k] = $v['b'];
  //$c[$k] = $v['c'];
}
 
 
 
array_multisort($a, SORT_ASC, $ar);
//array_multisort($a, SORT_DESC, $b, SORT_ASC, $ar);
 
print_r($ar);
