too long

Question

I'm self-studying the PHP language. And I'm focused on the latest PHP OOP language.

I search for some "ready-to-install" PHP software and as I scan for some references to search and know, I saw lines of code with a structure like this (can't remember so I'll create my own):

$myapp->settings->getValue('openforum');
$myapp->settings->setValue('closeformaintenance', '1');

So my question is, how can I reproduce the code above? I don't know what term to use that line of code (objects, I guess?).

Something like this:

$newLogin->search($uid)->setLogin($dateToday);

Like that. I really need to do that way so I can organize my coding structure. Thanks by the way.

And also for the final question, IS THAT POSSIBLE?

Answer 1

What you try to achieve is called method chaining. You can get this by the following:

<?php
class TestClass {
    private $val = '';

    public function test1($val) {
        $this->val = $val;
        return $this;
    }
    public function test2() {
        echo 'Hello '.$this->val;
    }
}

$test->test1('World')->test2(); // Hello World

You have simply to return the instance of the object on the method to allow the method chaining.
