PHP JSON转数组

<?php
$s='{"webname":"homehf","url":"www.homehf.com","qq":"744348666"}';
$web=json_decode($s); //将字符转成JSON
$arr=array();
foreach($web as $k=>$w) $arr[$k]=$w;

前三行可以用$web=json_decode($s,true)代替;

print_r($arr);
?>
 

<?php
function json_to_array($web){
$arr=array();
foreach($web as $k=>$w){
    if(is_object($w)) $arr[$k]=json_to_array($w); //判断类型是不是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);

//上一行可以用$web=json_decode($s,true)代替;
print_r($arr);
?>
