PHP实现数组转JSon和JSon转数组的方法示例
这篇文章主要介绍了PHP实现数组转JSon和JSon转数组的方法,结合实例形式分析了php数组与json相互转换实现方法与操作技巧,需要的朋友可以参考下。
本文实例讲述了PHP实现数组转JSon和JSon转数组的方法,分享给大家供大家参考,具体如下:
数组转JSon数据:
- $array_1 = array(); //一维数组
- $array_2 = array(); //多维数组
- $array_1['username']='ericwolf';
- $array_1['age']=25;
- $array_2['menber']['aa']['username']='ericwolf';
- $array_2['menber']['aa']['age']=25;
- $array_2['menber']['bb']['username']='eeee';
- $array_2['menber']['bb']['age']=22;
- print_r($array_2);
- $jsonObj_1 = json_encode($array_1);
- var_dump($jsonObj_1);
- $jsonObj_1 = json_encode($array_2);
- var_dump($jsonObj_1);
运行结果:
- Array
- (
- [menber] => Array
- (
- [aa] => Array
- (
- [username] => ericwolf
- [age] => 25
- )
- [bb] => Array
- (
- [username] => eeee
- [age] => 22
- )
- )
- )
- string(32) "{"username":"ericwolf","age":25}"
- string(84) "{"menber":{"aa":{"username":"ericwolf","age":25},"bb":{"username":"eeee","age":22}}}"
JSon转数组,并打印:
- $jsonStr = '{"key":"value","key1":"value1"}';
- $json2Array = json_decode($jsonStr,true);
- foreach($json2Array as $key=>$val) {
- echo $key."=".$val."<br/>";
- }
运行结果:
key=value
key1=value1
