PHP - Accessing Class Properties
Introduction
Once you've created a class property, you can access the corresponding object's property value from within your calling code by using the following syntax:
$object->property;
The property name doesn't have a $ symbol before it.
Here's an example that shows how to define properties then set and read their values:
Demo
<?php
class Truck {
public $color;
public $manufacturer;
} /*from w ww. j av a2 s . co m*/
$myTruck = new Truck();
$myTruck->color ="red";
$myTruck->manufacturer ="Niu";
$myTruck2 = new Truck();
$myTruck2->color ="green";
$myTruck2->manufacturer ="Ford";
echo "The usa's color is". $myTruck->color.".\n";
echo "The Mustang's manufacturer is". $myTruck2->manufacturer.".\n";
echo "The \$myTruck Object: \n";
print_r($myTruck);
echo "\n";
echo "The \$myTruck2 Object: \n";
print_r($myTruck2);
?>
Result
