2 PhP Questions

1. What means this line? Why we use -> in PHP??
$this->cookie_data = array('u' => 0, 'k' => '');

2. Can I execute the function which I created like:

function talk() {
echo "word";
}

.. by entering url like: talk.php?talk ??

Thanks in advance :)

the -> operator refers to a method or property of the class.

so if you have a class with the following properties:

name
address

you could access and modify them like this:

class->name = "myName";

echo class->name; //will print "myName"

thanks for first answer :)

Question 2:

Yes, like this:

file.php?action=something

file.php:

if($_GET['action'] == 'something') {
talk();
}

function talk() {
echo 'word';
}


The "action" parameter can be named whatever you want. You access it using the $_GET superglobal.

Another way of doing it is this.

if (isset($_GET["x"])) {
$x = explode(":",$_GET["x"]);

switch($x[0])
{
case 'talk':
talk();
break;

}
}

function talk() {
echo 'Hello';
}

That will give you this talk.php?x=talk
rename the X's to whatever word you want it to be.

Why the explode on the GET parameter?

Because if you had say a userid. You could do

talk.php?x=talk:71

But then why not just another GET so like talk.php?x=talk&id=71

:) nice ways to use this... thx again guys.

Take a look at http://php.net/manual/en/language.oop5.basic.php

it is needed to use public functions?? why not just functions?

Try googling object oriented programming (OOP) and read up on it. It is kind of hard to explain in a post. Try reading this one http://www.devarticles.com/c/a/PHP/Object-Oriented-Programming-in-PHP/
