PHP Realizes Array to JSon and JSon to Array Method Example

This paper describes the method of PHP converting array to JSon and JSon converting array. Share it for your reference, as follows:

Array to JSon data:

$array_1 = array(); //1 Dimensional array 
$array_2 = array(); // Multidimensional array 
$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);

Run results:

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 turns the array and prints:

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

Run results:

key=value
key1=value1
