PHP二维数组排序函数
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) ); $ShoppingList = array_sort($array,'price'); print_r($ShoppingList);
上面是对$array这个二维数组按照'price'从低到高的排序。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
