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($jsonStr,true);foreach($json2Arrayas$key=>$val){echo$key."=".$val."<br/>";}

运行结果:

key=value
key1=value1
