copied!<p>You are using a method (functions in objects are called methods) that is the same name as the class. That is called the constructor, it has a special meaning in OOP.</p> <p>The constructor is never called separately, but is the method that gets called automatically when you initialize the object. Any parameters that method has, you append to the <code>new classname</code> statement.</p> <pre><code>$test = new myClass(123); </code></pre> <p>also, the constructor must never return a value. It is used only to do things while initializing the class, e.g. storing parameters. Any returned values will be lost, as the result of <code>new myClass</code> is <em>always</em> the initialized object.</p> <p>If you are just looking to create a method inside your class to return some text, then you need to change the method's name. This would work:</p> <pre><code><?php class myClass { var $input; var $output; function someOtherFunctionName($input) { $output = 'You entered: ' . $input; return $output; } } $test = new myClass; echo $test->someOtherFunctionName(123); ?> </code></pre> <p>If a constructor is indeed what you want to use, then note that since PHP 5, it is standard practice to use <code>__construct()</code> instead of creating a method with the same name as the class:</p> <pre><code><?php class myClass { var $input; var $output; function __construct($input) { $this->input = $input; // This is a valid thing to do in a constructor } } </code></pre> <p>More on constructors and destructors in PHP 5 in the <a href="http://php.net/manual/en/language.oop5.decon.php" rel="nofollow noreferrer">manual</a>.</p>
