functions accessible by multiple php classes (Symfony controllers)

Question

I have a couple functions that are used in multiple controllers in my Symfony project. Instead of copy and pasting them constantly, I'd like to have a separate php file (say functions.php) to store the functions.

I've tried the following:

1) include and require the php file with the functions, but it won't let me use $this->getDoctrine(). I've looked at the following posts for help, but it didn't solve the issue:

Symfony2: get Doctrine in a generic PHP class

Symfony2 Use Doctrine in Service Container

2) I've tried making it a class and having the functions as methods then doing:

$f = new Functions();
$variable = $f->myMethod();

But it returns:

The file was found but the class was not in it, the class name or namespace probably has a typo.

Thanks for any help. I really appreciate it.

UPDATE:

The generic class is Symfony/src/WikiRoster/MainBundle/Controller/DBFunctions.php I just need to be able to use $this->getDoctrine() or the like somehow in there now. I've tried using the services.yml as suggested in the link above, but no cigar. Thanks!

Answer 1

The file was found but the class was not in it, the class name or namespace probably has a typo.

This issue happens quite often actually. As the error mentions, there are 2 cases explaining why this error is returned:

• If the namespace of your file is not the same as the path of your file
• If the name of your file is not the same as the name you are using in your class

Example

Let's say you would like to use a GeneralClass in a different class like that:

use  Acme\YourBundle\General\GenericClass

For this to work, GeneralClass needs to be in Acme/YourBundle/General/, and you need to:

• use the correct namespace: namespace Acme\YourBundle\General
• name your class with the same name: class GenericClass

You would have:

namespace Acme\YourBundle\General;

class GenericClass
{
    public function __construct()
    {
        // some cool stuff
    }
}
