PHP server terminated unexpectedly (Symfony) - php

Question

I've just started to learn Symfony framework and I noticed that almost every time there is some meaningful error in my code (for example I missed some "use" statement) my server terminates unexpectedly and I don't know how to get any information about what exactly caused it.
Most of the time I was able to figure it out on my own, but now I've just started to use Doctrine and I want to save some object to the database, but when I run the code my server terminates. I figured out that the "flush()" method is causing the problem, but now I'm stuck as I can't get any more information about the error. So I actually have two questions - how can I get more information about errors like this and how to solve this particiular one?
The codes are below:
The controller
/* UserController.php */
namespace AppBundle\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\HttpFoundation\Request;
use AppBundle\Entity\User;
use Symfony\Component\HttpFoundation\Response;
class UserController extends Controller
{
/**
* #Route("/user/test")
*/
public function testAction(Request $request)
{
$user = new User();
$user->setLogin("Test");
$user->setEmail("test#test.com");
$user->setPassword(hash("sha256", "test"));
$user->setJoined(date("Y-m-d H:i:s"));
$user->setActivationCode(NULL);
$em = $this->getDoctrine()->getManager();
$em->persist($user);
$em->flush(); /* The line that causes server to terminate! */
return new Response("Hello");
}
}
And the entity
/* User.php (Entity) */
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="`user`")
*/
class User
{
/**
* #ORM\Column(type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\Column(type="string", length=128)
*/
private $email;
/**
* #ORM\Column(type="string", length=64)
*/
private $login;
/**
* #ORM\Column(type="string", length=64)
*/
private $password;
/**
* #ORM\Column(type="datetime")
*/
private $joined;
/**
* #ORM\Column(type="string", length=64, nullable=TRUE)
*/
private $activation_code;
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set email
*
* #param string $email
*
* #return User
*/
public function setEmail($email)
{
$this->email = $email;
return $this;
}
/**
* Get email
*
* #return string
*/
public function getEmail()
{
return $this->email;
}
/**
* Set login
*
* #param string $login
*
* #return User
*/
public function setLogin($login)
{
$this->login = $login;
return $this;
}
/**
* Get login
*
* #return string
*/
public function getLogin()
{
return $this->login;
}
/**
* Set password
*
* #param string $password
*
* #return User
*/
public function setPassword($password)
{
$this->password = $password;
return $this;
}
/**
* Get password
*
* #return string
*/
public function getPassword()
{
return $this->password;
}
/**
* Set joined
*
* #param \DateTime $joined
*
* #return User
*/
public function setJoined($joined)
{
$this->joined = $joined;
return $this;
}
/**
* Get joined
*
* #return \DateTime
*/
public function getJoined()
{
return $this->joined;
}
/**
* Set activationCode
*
* #param string $activationCode
*
* #return User
*/
public function setActivationCode($activationCode)
{
$this->activation_code = $activationCode;
return $this;
}
/**
* Get activationCode
*
* #return string
*/
public function getActivationCode()
{
return $this->activation_code;
}
}

Answer 1

Use web/app_dev.php as your endpoint.
So your url will be like localhost:8000/app_dev.php/<your-routing-alias>

Answer 2

Are you using a web browser to access your Symfony instance on a remote host - I mean a machine that is not the 'localhost'? If so, you'll need to edit the 'web/app_dev.php' file where it has a line like so:
|| !(in_array(#$_SERVER['REMOTE_ADDR'], ['192.168.40.208', '192.168.255.74',
'127.0.0.1', 'fe80::1', '::1']) || php_sapi_name() === 'cli-server')
Enter in the IP address of the remote host that you are trying to access your web URL from. Using the DEV URL: of "http://ip_address/app_dev.php/" would be the best way to troubleshoot.
You'll see useful help information when you use this link - I highly recommend it.
I also notice this one line:
#ORM\Table(name="`user`")
I'm not sure if you need those backticks. Try this:
#ORM\Table(name="user")

Answer 3

I recently had this issue and after a lot of investigation discovered the date was causing my issue. I can see this is an old question, but the answer may help someone.
It looks like Doctrine requires a full date time object when inserting into a datetime / datetimetz field:
Try replacing
$user->setJoined(date("Y-m-d H:i:s"));
With
$user->setJoined(new \DateTime("now"));
