If a property or method is static, it means it is a class attribute as opposed to being an instance attribute.
You will access a class attribute without needing to instantiate the class
E.g

class Example{
    public static $variable = "myValue";
}

The static variable can then be accessed by doing :

Example:: variable

The same thing for a method.


Unlike a situation where you'd have to do:

$myobj = new Example();
$myobj.variable

I believe it makes more sense now

In order to simplify what the ftc said.

Static keyword is used when you want to call that function/variable without instantiating the class itself.

Class Yay {
Public function happy() {
Return 'happy';
}
}

To use the function happy
You'll have to instantiate the Yay class
//Class yay is instantiated
$emotion = new Yay();
$emotion->happy();

Whereas static functions can be called with the class being instantiated.


Class Yay {
Public static function happy() {
Return 'happy';
}
}

//To access yay
Yay::happy();

Dot operator is Javascript not PHP, You've been writing way too much js.

Lol, my bad
I'm so used to Java actually, I only write a little js
Op, in my original answer the .(dots) should be replaced with ->

Hope you happy now?
And hope you didn't abandon java for php

Lol, I have always been happy.

I didn't exactly abandon Java for php, but all the serious jobs I have done have been in php.

OP, you understand well now right ?

So no need to explain again
