JSON PHP中,Json字符串反序列化成对象/数组的方法

<?php//php反编码解析json信息//json_decode(json字符串);$city = array('shandong'=>'jinan','henan'=>'zhengzhou','hebei'=>'shijiazhuang');$jn_city = json_encode($city);//反编码json$fan_city = json_decode($jn_city,false);//第二个参数false则返回object类型，false可以默认不写var_dump($fan_city);//object(stdClass)#1 (3) { ["shandong"]=> string(5) "jinan" ["henan"]=> string(9) "zhengzhou" ["hebei"]=> string(12) "shijiazhuang" } echo "<br />";$fan_city = json_decode($jn_city,true);//第二个参数true则返回array类型var_dump($fan_city);//array(3) { ["shandong"]=> string(5) "jinan" ["henan"]=> string(9) "zhengzhou" ["hebei"]=> string(12) "shijiazhuang" }

<?php  //json信息反编码  //不同php版本，对“纯json字符串”解析存在问题 //使用双引号定义的json字符串反编码操作变为null //$jn = "{'name':'tom','age':'20','addr':'beijing'}"; //$fan_jn = json_decode($jn,true); //var_dump($fan_jn);//NULL  //使用单引号定义的json字符串反编码操作会成功 $jn = '{"name":"tom","age":"20","addr":"beijing"}'; $fan_jn = json_decode($jn,true); var_dump($fan_jn);
