php获取通过url的json数据，返回的是空值

http://php.net/api/apply.php?&apply={"apply":{"name":"4747474","site":"http:\/\/4444444444444444","icon":"47","information":"474","about":"747","weibo":"74444444444","email":"74444444444444444","moblie":"89742589633","isfree":"y","applytime":1349939108}}

这个是一个链接，我在这个页面上要怎么把那段json格式给接下出来呢？

回复讨论(解决方案)

$x = json_decode($_GET['apply']);

$x = json_decode($_GET['apply']);

得出来还是空值，可能那个字符串存在错误吧...

var_dump(json_decode($_GET['apply'],true));
看?出什麽？

var_dump(json_decode($_GET['apply'],true));
看?出什麽？

NULL

var_dump(json_decode(urldecode($_GET['apply']),true));

var_dump(json_decode(urldecode($_GET['apply']),true));

也是不行，最后我把那些多余的\去掉了，不知道是为啥啊？

print_r(json_decode('{"apply":{"name":"4747474","site":"http:\/\/4444444444444444","icon":"47","information":"474","about":"747","weibo":"74444444444","email":"74444444444444444","moblie":"89742589633","isfree":"y","applytime":1349939108}}'));

stdClass Object(    [apply] => stdClass Object        (            [name] => 4747474            [site] => http://4444444444444444            [icon] => 47            [information] => 474            [about] => 747            [weibo] => 74444444444            [email] => 74444444444444444            [moblie] => 89742589633            [isfree] => y            [applytime] => 1349939108        ))

PHP code
print_r(json_decode('{"apply":{"name":"4747474","site":"http:\/\/4444444444444444","icon":"47","information":"474","about":"747","weibo":"74444444444","email":"74444444444444444","moblie":"……

嗯，谢谢了

LZ地址中参数apply前面多了个&符号，你看会不会是这个的问题

之前是我的文本格式有问题，得出来的结果有错误

$json_string = $_GET["apply"];
 if(ini_get("magic_quotes_gpc")=="1")
 {
  $json_string=stripslashes($json_string);
 }
