PHP

Create a Bicycle class. Class attributes include: brand, model, year, description, and weight_kg (weight in kilograms).

Write three methods (functions) for the Bicycle class: name, weight_pounds, and set_weight_pounds. The name function should return the concatenation of brand, model, and year. The weight_pounds function should convert kilograms to pounds (kg * 2.2046226218) and return it as a floatval data type. The set_weight_pounds function should convert pounds to kilograms ( floatval($value) / 2.2046226218). When the set_weight_pounds function is called, it also passes to the function the weight in pounds. The function then converts $value to kilograms.

Create two objects and set the each of the properties for the objects. Then display the name of each object, the weight in kilograms, and the weight in pounds.

   }
   //function to convert kg to pounds
    function weight_pounds() {
       //returning the weight in pound

   }
   //function yo get the weigth in kg
   function set_weight_pounds($value){
       //returning value in kg
       return floatval($value) / 2.2046226218;
   }
   //end of class
}
//creating first object
$obj = new Bicycle("Avon","Atlas",2012,"heavy duty ", 23.5);
//calling function to get the name
echo "Name is ". $obj->name();
//moving to new line
echo "<br>";
//calculating the weight in pounds by calling function and storing the value
$weight=$obj->weight_pounds();
//printing the weight in pounds
echo "Weight in pounds is $weight";
//moving to new line
echo "<br>";
//calling function to convert the pounds weight in kg again
echo "Weight in kg is ". $obj->set_weight_pounds($weight);

//moving to new line
echo "<br>";
//creating Second object
$obj1 = new Bicycle("Hercules","Ninza",2018,"Terrain", 12.6);
//calling function to get the name
echo "Name is ". $obj1->name();
//moving to new line
echo "<br>";
//calculating the weight in pounds by calling function and storing the value
$weight=$obj1->weight_pounds();
//printing the weight in pounds
echo "Weight in pounds is $weight";
//moving to new line
echo "<br>";
//calling function to convert the pounds weight in kg again
echo "Weight in kg is ". $obj1->set_weight_pounds($weight);

?>
