Method Parameters in PHP

Since a method is essentially a regular function, it can accept parameters just like all functions. Let's make our method show from the previous lesson accept some string as a parameter and add '!!!' to its end:

php<?php
  class User
  {
    public $name;
    public $age;
    
    public function show($str)
    {
      return $str . '!!!';
    }
  }
?>

Let's create a user object:

php<?php
  $user = new User;
  $user->name = 'john';
  $user->age = 25;
?>

Let's call our method:

php<?php
  echo $user->show('hello'); // will output 'hello!!!'
?>
