PHP sorts a given two-dimensional array according to the specified key value
<?php //PHP一维数组的排序可以用sort(),asort(),arsort()等函数,但是PHP二维数组的排序需要自定义。 //以下函数是对一个给定的二维数组按照指定的键值进行排序,先看函数定义: function array_sort($arr,$keys,$type='asc'){ $keysvalue = $new_array = array(); foreach ($arr as $k=>$v){ $keysvalue[$k] = $v[$keys]; } if($type == 'asc'){ asort($keysvalue); }else{ arsort($keysvalue); } reset($keysvalue); foreach ($keysvalue as $k=>$v){ $new_array[$k] = $arr[$k]; } return $new_array; } //它可以对二维数组按照指定的键值进行排序,也可以指定升序或降序排序法(默认为升序),用法示例: $array = array( array('name'=>'手机','brand'=>'诺基亚','price'=>1050), array('name'=>'笔记本电脑','brand'=>'lenovo','price'=>4300), array('name'=>'剃须刀','brand'=>'飞利浦','price'=>3100), array('name'=>'跑步机','brand'=>'三和松石','price'=>4900), array('name'=>'手表','brand'=>'卡西欧','price'=>960), array('name'=>'液晶电视','brand'=>'索尼','price'=>6299), array('name'=>'激光打印机','brand'=>'惠普','price'=>1200) ); //下面是对$array这个二维数组按照'price'从低到高的排序。 $ShoppingList = array_sort($array,'price'); print_r($ShoppingList);
The above introduces PHP to sort a given two-dimensional array according to the specified key value, including aspects of the content. I hope it will be helpful to friends who are interested in PHP tutorials.
