PHP Class :: Hello World

[miiikkeyyyy]

Here is my code:

<?php

class Test {
function hello()
{
	echo"hello";
}

public function &world()
{
	echo" world";
}
}

$test = new Test();
$test->hello()
      ->world();

?>

 

I know it can be done like:

$test = new Test();
$test->hello();
$test->world();
?>

 

However I want it too look like: (as I believe it's cleaner)

$test = new Test();
$test->hello()
     ->world();
?>

So, what's the problem?  And why are you using the reference operator with your second method?

[Jessica]

The only way that would work is if hello() returns an object that has the method world();

 

Just because you like the way it looks doesn't mean it's better :-P

The first example is correct.

$test->hello();

$test->world();

First of all, remove the reference character (&) from

	public function &world()

. PHP5 doesn't need references.

 

To allow method chaining, just return $this from every method you want to be chainable.

 

function hello()
{

echo"hello";	

return $this;

}

add

 

return $this;

 

to hello() and world() remove the reference-operator (&) as objects are passed by reference by default.

 

PHP5 doesn't need references

 

Sure it does, especially when passing big array's.
