Symfony Doctrine Many to Many Relationship (ManyToMany)

Many to many relations are one of the mostly used relations in the relational database. It took a while for me to figure how to properly configure this relation in Symfony Doctrine. I am sharing this so it might be useful for someone.

Used very simple example students and course. A student can opt for multiple courses and a single course can be opted by multiple students.

And Entity class should be like this…

The above entities will create the following SQL and it will also create the cross-reference table.

Hope this helps 😉

Why do we need to upgrade PHP 5.6 to PHP 7.2?

Rest in peace PHP 5.6

  • The current version of PHP which is 5.6 has reached the end of life on 19th Jan 2017. PHP team has stopped support for 5.6, and no more new features added.
  • Security support for 5.6 is up to Jan 2019. On Jan 2019 PHP 5.6 officially dead.
  • The newer version of Linux and server software has already stopped supporting PHP 5.6 which creates a huge security risk.
  • Updating old server will be hard as it may break the PHP due to compatibility issues.
  • All major PHP libraries and frameworks will drop support for PHP 5.6
  • 7.2 end of life is in Jan 2021
  • 7.2 is so much faster than 5.6
  • 7.X has new Zend Engine
  • Reduction in the memory usage

Symfony: Adding custom route by code during runtime

During development we always come across situation where you need to add custom routes based on some settings based from the user. In this case we cannot use any of the standard methods like annotation and configuration files in symfony.

In this case you need to use a services and hooks to inject your custom route rules during runtime.

1) In your bundles under Resources\Config\services.yml add the following

2) Now we need to create a class RoutingService.php

3) Now in your main routing.yml please include these lines

4) Once you are done please make sure you clear cache both env

5) Now the custom route should be loaded in.. Please make sure if you add more routes make sure the cache is cleared.
