讲述了php实现多维数组排序的方法。分享给大家供大家参考，具体如下：
//定义一个学生数组$students = word">array( 256=>word">array('name'=>'jon','grade'=>98.5), 2=>array('name'=>'vance','grade'=>85.1), 9=>array('name'=>'stephen','grade'=>94.0), 364=>array('name'=>'steve','grade'=>85.1), 68=>array('name'=>'rob','grade'=>74.6),);//按照名称进行排序function name_sort($x, $y){ return strcasecmp($x['name'],$y['name']);}//按照成绩进行排序function grade_sort($x,$y){ return ($x['grade'] > $y['grade']);}//应用uasort($students, name_sort);uasort($students, grade_sort);
