反序列化PHP类和gz膨胀的问题

我正在尝试序列化一个类(用户)并将其作为GET变量传递到下一页。

下面是我的测试代码:

$usr->getByLoginPass($db,"perf@stud.de","a32636ba1c7875b19c6f32121078c2da0be6f857");
$serial = $usr->serialize();
$handle = fopen("http://localhost/newClassSite/utests/userSerializationTest.php?data=$serial", "rb");
$contents = "";
while (!feof($handle)) {
    $contents .= fread($handle, 8192);
}
fclose($handle);
if(strpos($contents,"Perfect") === false) {
    echo"$contents<br>";
    echo"Problem with serialization testUser.test:16" . $usr->getLastError() . "<br>";
}

以下是userSerializationTest.php中的代码:

$data = $_GET['data'];
echo"5: $data<br>";
include('../user.inc');
$usr = new User();
$usr->deserialize($data);
$usr->printUser();

下面是类中的代码:

public function serialize() {
    $serial = serialize($this);
    $df = gzdeflate($serial);
    $b64 = base64_encode($df);
    $ue = urlencode($b64);
    echo "<font face='Courier New'>1: $serial<br><br>2: $df<br><br>3: $b64<br><br>4: $ue<hr><br>";
    return($ue);
}
public function deserialize($data) {
    $ud = urldecode($data);
    $u64 = base64_decode($ud);
    $gf = gzinflate($u64);
    $us = unserialize($gf);
    echo"6: $ud<br><br>7: $u64<br><br>8: $gf<br><br>9: $us<hr><br>";
}

输出如下:

我希望字段在最后填写。
为什么gzinflation失败了?
我遗漏了什么?
