$arr = array('a'=>1,'c'=>3,'b'=>2);
asort($arr);
这样的排序我已经知道了
但是 如果一个二维数组
$arr[] = array('name'=>'a','flag'=>1);
$arr[] = array('name'=>'b','flag'=>2);
$arr[] = array('name'=>'a','flag'=>1);
我只想根据 键flag为的值 进行排序
期望的效果为:
$arr[] = array('name'=>'a','flag'=>1);
$arr[] = array('name'=>'a','flag'=>1);
$arr[] = array('name'=>'b','flag'=>2);
希望大家帮帮忙
这个是C++版，不知道有没有会PHP的专家来回答你的问题，还是赶紧结贴吧
$arr[] = array('name'=>'a','flag'=>1);$arr[] = array('name'=>'b','flag'=>2);$arr[] = array('name'=>'a','flag'=>1);$flag=array();foreach($arr as $arr2){ $flag[]=$arr2["flag"]; }array_multisort($flag, SORT_ASC, $arr);print_r($arr);谢谢，知道了
