php json轉數組(使用PHP怎么對數組和JSon進行轉換)

數組轉JSon數據:

$array_1=array();//一維數組$array_2=array();//多維數組$array_1['username']='ericwolf';$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);

運行結果:

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轉數組,并打印:

$jsonStr='{"key":"value","key1":"value1"}';$json2Array=json_decode($jsonStr,true);foreach($json2Arrayas$key=>$val){echo$key."=".$val."<br/>";}

運行結果:

key=value
key1=value1
