symfony2：生产服务器上的ContextErrorException“用于反序列化的错误数据格式”

Question

I want to deploy symfony2 application. On localhost works perfect, the only difference my web directory is in public_html, but when I installed on my prod server, after register some user, the exception has been thrown. Looks like unserializing can't decode, my entity "0:{}":

ContextErrorException: Warning: Erroneous data format for unserializing 'CodeCats\PanelBundle\Entity\User' in /home/progress/domains/progress-checker.pl/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php line 869

Ok it's the issue (and possible solutions):

Answer 2

For those still coming across this issue, updating the doctrine/orm dependency worked.

My new doctrine dependency line in composer.json: "doctrine/orm": ">=2.2.3,<2.5",

Then I updated composer as per usual from the command line: php composer.phar update

Answer 3

Since it's the top Google result for this error I'll just paste the dirty quick fix here to get you going more easily.

Note: In nearly every case you shouldn't modify any vendor files like this. However, if you have some dependency problem which couldn't be solved for some reason here's the trick for you.

This is a Doctrine error, so you should modify the Doctrine ORM bundle a bit.

Add your PHP_VERSION_ID to the newInstance() function in

/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php

The final result looks like this for me:

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;
}

Answer 4

I had the same issue. I solved it by updating "doctrine/orm" package in Composer.json to "~2.4" version and then running:
composer update doctrine/orm
from the command line. This should only update the concerned package. After this refreshing the webpage and/or logging in again and the error was gone.
Hope this helps.
