PHP JSON to array

$s='{"webname":"homehf","url":"www.homehf.com","qq":"744348666"}';
$web=json_decode($s); //Convert characters to JSON
$arr=array();
foreach($web as $k=>$w) $arr[$k]=$w;< ;/p>
The first three lines can be replaced by $web=json_decode($s,true);
print_r($arr);
?>

In the above code, a JSON object has been converted into an array, but if it is a nested JSON, the above code is obviously useless, so we write a function to solve the nested JSON ,

function json_to_array($web){
$arr=array();
foreach($web as $k=>$w){
 if(is_object ($w)) $arr[$k]=json_to_array($w); //Judge whether the type is object
 else $arr[$k]=$w;
}
return $arr;
}
$s='{"webname":"homehf","url":"www.homehf.com","contact":{"qq":"744348666","mail":"nieweihf @163.com","xx":"xxxxxxx"}}';
$web=json_decode($s);
$arr=json_to_array($web);
//Up One line can be replaced by $web=json_decode($s,true);
print_r($arr);
?>

The custom json_to_array() method can convert any Convert nested JSON to array.
