php数组转换json字符串的方法:首先创建一个php示例文件;然后定义一组数组数据;最后通过“json_encode($color)”方法将数组转换成json字符串即可。

PHP中 数组/对象转成JSON字符串
代码如下:
<?php //php语言生成json字符串 //json_encode(数组/对象); //① 索引数组-->JavaScript数组 $color = array('gold','yellow','blue'); echo json_encode($color)."<br />";// ["gold","yellow","blue"] //② 关联数组-->json字符串 $city = array('shandong'=>'jinan','henan'=>'zhengzhou','hebei'=>'shijiazhuang'); echo json_encode($city)."<br />";//{"shandong":"jinan","henan":"zhengzhou","hebei":"shijiazhuang"} //③ 索引关联数组-->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 对象生成json信息-->json字符串 // (只会序列化"成员属性",不会序列化"成员方法") class Person{ //类内部的成员属性需要有修饰符(var/public/protected/private),其是固定语法 public $color = "yellow"; var $height = 170; function run(){ echo "is running"; } } $tom = new Person(); echo json_encode($tom); //{"color":"yellow","height":170}
