In order to access attributes in a class itself we need to use ‘this’ keyword. This is the object in use right now in class while we are working. We can try to price $this at any time to show its condition. I am going to do this. So imagine this product class in our shop scenario.
class Product {
public $name;
public $priceWithoutTaxes;
public $tax;
public $priceWithTax;
public function setName( $name ) {
$this->name = $name;
}
public function setPriceWithoutTax( $priceWithoutTaxes ) {
$this->priceWithoutTaxes = $priceWithoutTaxes;
}
public function setTax( $tax ) {
$this->tax = $tax;
}
public function setPriceWithTax() {
$this->priceWithTax = $this->priceWithoutTaxes + $this->tax;
}
}
Now lets write the code for it and actually use this class.
$product = new Product();
$product->setName( 'Purel' );
$product->setPriceWithoutTax( 45 );
$product->setTax( 5 );
$product->setPriceWithTax();
Lets say we will print $this in setPriceWithTax function. So code will change just a little.
public function setPriceWithTax() {
print_r($this);
$this->priceWithTax = $this->priceWithoutTaxes + $this->tax;
}
And you will observe this output
.
