Answer 1

This code works for me, YourApplicationName\vendor\doctrine\lib\Doctrine\ORM\Mapping\ClassMetadataInfo.php

i replace the existing code with the below code

If ($this->_prototype === null) {
    $this->_prototype = @unserialize(sprintf('O:%d:"%s":0:{}', strlen($this->name), $this->name));
if ($this->_prototype === false) {
    $this->_prototype = unserialize(sprintf('C:%d:"%s":0:{}', strlen($this->name), $this->name));
}
}

1. Check your PHP version by "php -v" on command line. E.g. PHP 5.6.10

2. Edit the file /vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php::newInstance()

Add your PHP_VERSION_ID here

if (PHP_VERSION_ID === 50610 ) {
.
}

It's a temporary solution, since we don't edit vendor directory.

I experienced the same problem with php 5.6.6 (locally with mamp), my workaround was just to go back to 5.4, since that's the version I had running on the Server anyways... but definately something to keep in mind...

Answer 4

If you are using PHP Version 5.4.29 or 5.5.13

In: "/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php" find function "newInstance" (around Line 827) and edit as followed until the Fix is merged by doctrine.

public function newInstance()
{
    if ($this->_prototype === null) {
        // $this->_prototype = unserialize(sprintf('O:%d:"%s":0:{}', strlen($this->name), $this->name));
        if (PHP_VERSION_ID === 50429 || PHP_VERSION_ID === 50513) {
            $this->_prototype = $this->reflClass->newInstanceWithoutConstructor();
        } else {
            $this->_prototype = unserialize(sprintf('O:%d:"%s":0:{}', strlen($this->name), $this->name));
        }
    }
    return clone $this->_prototype;
}

Answering my own question, I found a workaround thanks to this guy :

http://www.doctrine-project.org/jira/browse/DDC-3120

He's far better than me when it comes to explaining, but this is what I have now, and it works like a charm! :)

{
        if ($this->_prototype === null) {
            $this->_prototype = @unserialize(sprintf('O:%d:"%s":0:{}', strlen($this->name), $this->name));
            if ($this->_prototype === false) {
                $this->_prototype = @unserialize(sprintf('C:%d:"%s":0:{}', strlen($this->name), $this->name));
            }
        }

        return clone $this->_prototype;
    }
