PHP对象和数组互转的方法
在php开发网站的时候，经常要将两种数据类型相互转化，以便使用。
下面介绍PHP对象和PHP数组将的相互转化方法：
（1）php对象转数组的方法：
<span style="font-size: 14px;">/**</span><br /> * object 转 array<br /> */<br />function object_to_array($obj){<br />$_arr=is_object($obj)?get_object_vars($obj):$obj;<br />foreach($_arr as $key=>$val){<br />$val=(is_array($val))||is_object($val)?object_to_array($val):$val;<br />$arr[$key]=$val;<br />}<br />return $arr;<br /><p>}<span style="font-size: 14px;">（2）php Json字符转数组的方法：
如果是个 json 字符串的话，可直接通过 json_decode 函数将字符串转换成数组。
json_decode (PHP 5 >= 5.2.0, PECL json >= 1.2.0)json_decode — 接受一个 JSON 格式的字符串并且把它转换为 PHP 变量mixed json_decode(string $json[,bool $assoc])参数:json 待解码的 json string 格式的字符串。
assoc 当该参数为 TRUE 时，将返回一个数组（关联数组）形式的结果，默认为false，返回的是一个对象。

Which is faster, php object operation or array operation?
Jul 12, 2023 pm 03:04 PM
