First, I apologize if this is the wrong venue, but it seemed the best place to ask question about code. The code below is very simple most likely, but I am having the hardest time visualizing how it's run. It would be most helpful if someone could point out the error of my thinking that would be awesome. This is literally the first php lesson I have ever taken.
I'm a very visual, hands on kind of learner. It would be most appreciated to get direction into the best way to learn PHP as a visual learner. Thanks!
<?php
// I'm following an example online and need an explanation to this. This first part is creating
// a class called User.
class User {
// This is a variable set to public. Now in the lesson I discovered public and private. Why is
// public and private important? Could the code just run on $age?
public $age;
// This is a public function called __construct. Could I name this anything and the function
// would still work? What is important about __?
public function __construct($age) {
// Ok, why is $this used? Is it correct in assuming that any word with a "$" assigned to it in
// this class will refer to age?
$this->age = $age;
}
// This is the 3rd function called getAge(). Why is getAge() blank?
public function getAge() {
echo $this->age;
}
}
// Shoudln't this be at the top? And isn't there a cleaner way to output the age of a new user?
// This seems to take up way too much coding just to display the name of a variable?
$brad = new User(31);
// I'm so confused.
$brad->getAge();
