PHP中 數組/對象轉成JSON字符串

代碼如下：

<?php   //php語言生成json字符串 //json_encode(數組/對象);   //① 索引數組-->JavaScript數組 $color = array('gold','yellow','blue'); echo json_encode($color)."<br />";// ["gold","yellow","blue"]   //② 關聯數組-->json字符串 $city = array('shandong'=>'jinan','henan'=>'zhengzhou','hebei'=>'shijiazhuang'); echo json_encode($city)."<br />";//{"shandong":"jinan","henan":"zhengzhou","hebei":"shijiazhuang"}   //③ 索引關聯數組-->json字符串 $city2 = array('shandong'=>'jinan','henan'=>'zhengzhou','shenyang','hebei'=>'shijiazhuang'); echo json_encode($city2)."<br />";//{"shandong":"jinan","henan":"zhengzhou","0":"shenyang","hebei":"shijiazhuang"}   //④ 對象生成json信息-->json字符串 //   (只會序列化"成員屬性"，不會序列化"成員方法") class Person{     //類內部的成員屬性需要有修飾符(var/public/protected/private)，其是固定語法     public $color = "yellow";     var $height = 170;     function run(){         echo "is running";     } } $tom = new Person(); echo json_encode($tom);  //{"color":"yellow","height":170}
