实现数组转Json和Json转数组的方法示例 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
