Using more than 1 function in-line from class

Question

How can i use a more than 1 function inline from object? I have simple class:

class test
{
    private $string;

    function text($text)
    {
        $this->string = $text;
    }

    function add($text)
    {
        $this->string .= ' ' . $text;
    }
}

so how i can use this class as:

$class = new test();
$class->text('test')->add('test_add_1')->add('test_add_2');

not like:

$class = new test();
$class->text('test')
$class->add('test_add_1')
$class->add('test_add_2')

And at end in class $string will be: test test_add_1 test_add_2

I believe you have to `return $this` at the end of the function — Djave, Dec 30 '14 at 22:45

You return $this so you can then continue work on the object:

class test
{
    private $string;

    function text($text)
    {
        $this->string = $text;
        return $this;
    }

    function add($text)
    {
        $this->string .= ' ' . $text;
        return $this;
    }
}
