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
