Difference between passing objects by reference and without in PHP

Quite often I here, that people don't understand, how to use variables by reference. PHP is not an exception. This will be a very short post in which I will try to make it clear.
First of all we will define simple object class A.

class A
{
	protected $foo;
	
	public function __toString()
	{
		return $this->getFoo();
	}
	
	public function setFoo( $foo )
	{
		$this->foo = $foo;
	}
	
	public function getFoo()
	{
		return $this->foo;
	}

How to fix Doctrine 1.2.4 Base models autoloading

I must say right away, that I don't know how correct this fix is, but it works for me. So in Doctrine ORM 1.2.4 after generating models I ran in a bit of a problem. So I fixed like that:
Find file vendor\doctrine\doctrine1\lib\Doctrine\Core.php
Next on line 1155 find this code:

$class = self::$_modelsDirectory . DIRECTORY_SEPARATOR . str_replace('_', DIRECTORY_SEPARATOR, $className) . '.php';

            if (file_exists($class)){
                require $class;

                return true;
            }

And add this code after:

$class = self::$_modelsDirectory . DIRECTORY_SEPARATOR . 'generated' . DIRECTORY_SEPARATOR . str_replace('_', DIRECTORY_SEPARATOR, $className) . '.php';

            if (file_exists($class)) {
                require $class;

                return true;
            }

This is it.

How to run Redis server as daemon

So I think, that those who will read this article probably know, what is Redis. For those who don't I can say shortly, that this is a software, that is used for storing some maped data ( key => value ) for faster usage.

In this article I will shortly explain how to make your Redis server run as daemon, since making startup file for this in unix is not an option.
