PHP中把stdClass Object转array(对象转数组)的几个方法

我们在经常使用API接口获取数据返回json数值的时候,往往单纯通过json_decode方法解析获得得数值一般并非数组,而是带有stdClass Objec的对象字符串,这时如果我们想获取相应的PHP数组时,需通过以下几种方法来获取。

 

方法一:

//PHP stdClass Object转array  
function object_array($array) {  
    if(is_object($array)) {  
        $array = (array)$array;  
     } if(is_array($array)) {  
         foreach($array as $key=>$value) {  
             $array[$key] = object_array($value);  
             }  
     }  
     return $array;  
}
Copy after login

 

方法二:

$array = json_decode(json_encode(simplexml_load_string($xmlString)),TRUE);
Copy after login

 

方法三:

 function object2array_pre(&$object) {
        if (is_object($object)) {
            $arr = (array)($object);
        } else {
            $arr = &$object;
        }
        if (is_array($arr)) {
            foreach($arr as $varName => $varValue){
                $arr[$varName] = $this->object2array($varValue);
            }
        }
        return $arr;
}
Copy after login

 

如果是10W的数据量的话,执行要进1s,结构再复杂些,可以达到3s, 性能太差了
可以用以下替换:
 

function object2array(&$object) {
  $object =  json_decode( json_encode( $object),true);
  return  $object;
}
Copy after login

 但是对json的特性,只能是针对utf8的,否则得先转码下。

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.

Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
