我想部署symfony2应用程序。在localhost工作完美，我的web目录唯一的区别在于public_html，但是当我在我的prod服务器上安装时，在注册一些用户之后，抛出了异常。看起来反序列化无法解码，我的实体“0：{}”：

其他信息：启用了神奇的gpc。

好的是问题（以及可能的解决方案）：
答案 1 :(得分：1)
对于那些仍然遇到此问题的人来说，更新doctrine / orm依赖有效。
我在composer.json中的新学说依赖行： ＆＃34; doctrine / orm＆＃34;：＆＃34;＆gt; = 2.2.3，＆lt; 2.5＆＃34;，
然后我按照惯例从命令行更新了composer：php composer.phar update

由于这是Google出现此错误的最高结果，因此我只需将脏快速修补程序粘贴到此处即可让您轻松上手。
注意：几乎在每种情况下都不应该像这样修改任何供应商文件。但是，如果你有一些因某些原因无法解决的依赖性问题，这就是你的诀窍。
这是一个Doctrine错误，因此您应该稍微修改一下Doctrine ORM包。
将您的PHP_VERSION_ID添加到
newInstance()功能
/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php
最终结果对我来说是这样的：
public function newInstance()
{
// echo PHP_VERSION_ID; die(); // Uncomment this, in case you don't know your PHP_VERSION_ID
if ($this->_prototype === null) {
if (PHP_VERSION_ID === 50429 || PHP_VERSION_ID === 50513 || PHP_VERSION_ID === 50603 || PHP_VERSION_ID === 70009) { // This is the tricky line
$this->_prototype = $this->reflClass->newInstanceWithoutConstructor();
} else {
$this->_prototype = unserialize(sprintf('O:%d:"%s":0:{}', strlen($this->name), $this->name));
}
}
return clone $this->_prototype;
}

我有同样的问题。我通过将Composer.json中的“doctrine / orm”包更新为“~2.4”版本，然后运行：
作曲家更新原则/ orm
从命令行。这应该只更新相关的包。在刷新网页和/或再次登录之后，错误消失了。
希望这会有所帮助。
