Using this
You should also know this before you can test the restrictor. ㅜㅜ
this is I'd like to use in my classes. Used to access a property or method declared in a class.
How to use properties using this
this->propertyname;
How to use a method using this
this-> method name();
Don't know what I'm talking about yet? You can use it like this:
Here is an example of using a property in a method:
<?php class Car { public $wheels = 4; public function checkWheelsCount() { return "This car has {$this->wheels} wheels."; } } $honda = new Car; echo $honda->checkWheelsCount(); ?>
Result
In other words, you should not use $wheels in a class like this: $this->wheels.
The following is an example of calling another method from a method of a class.
<?php class Car { public $wheels = 4; public function checkWheelsCount() { return $this->wheels; } public function outputWheelsCount() { return "This car has {$this->checkWheelsCount()} wheels."; } } $honda = new Car; echo $honda->outputWheelsCount(); ?>
Result
The code above functions that the method checkWheelsCount() returns the wheels property and called checkWheelsCount() in the outputWheelsCount() method.
