What are the other benefits other than that?

So basically, if you know C++, it is just like having a set of curly brackets, it is for namespace issues?

The game could have created the function getSysteminfo

Why would $A->Foo work but not A::Foo?

Sorry... didn't post the code... <?php class A { function foo() { if (isset($this)) { echo '$this is defined ('; echo get_class($this); echo ")\n"; } else { echo "\$this is not defined.\n"; } } } class B { function bar() { A::foo(); } } $a = new A(); $a->foo(); A::foo(); $b = new B(); $b->bar(); B::bar(); ?>

In this PHP.NET code, does the A::Foo not work because you are calling foo without... umm -> allows for $this to be used while :: does not?

What other benefits are there?

I did. So the only reason to have a class is to allow for the variable to be used again without worries?

I still don't get it. Can you give me a practical use?

I still don't see the point. Why not just set the variables in the page?

I still do not understand what a class does and why it should be used. Please explain it's use(s) and if needed, compare it to other PHP functions and features. Max

Try this: <?php function validateusername($val){ global $continueSubmit ; $result = mysql_query("SELECT * FROM `user` WHERE `username` = '$val' LIMIT 1"); $numrows = mysql_num_rows($result); $userlen = strlen($val); //check for blank username if($val == ''){ $continueSubmit = false; echo "<img src=\"/images/bad.gif\" alt=\"Bad\"> Field Required"; } else if($numrows > 0){ $continueSubmit = false; echo "<img src=\"/images/bad.gif\" alt=\"Bad\"> Username in use"; } else if($userlen > 50){ $val = false; echo "<img src=\"/images/bad.gif\" alt=\"Bad\"> Username Too Long. Please enter a username between 5 and 50 characeters."; } else if($userlen < 5){ $val = false; echo "<img src=\"/images/bad.gif\" alt=\"Bad\"> Username Too Short. Please enter a username between 5 and 50 characeters."; } else { //everything ok with username echo "<img src=\"/images/good.gif\" alt=\"Good\">"; } } ?>

you spelled mysql_num_rows as mysql_numrows

Change usernameTaken to: function usernameTaken($val){ $result = mysql_query("SELECT * FROM `user` WHERE `username` = '$val' LIMIT 1"); return (mysql_numrows($result) > 0); }

Nvm... I can just add in another if statement...

<?php if(isset($_POST['login'])){ // If Login Form was Sent if(empty($_POST['user'])){ echo "You have not provided a username."; } if(empty($_POST['pass'])){ echo "You have not provided a password."; } // If user or pass are empty, exit if statement // More code including if statements } ?>

Is it possible to break out of an if statement? I cannot use die because it finishes the execution of the whole page. How can I exit from one if statement?

I don't understand... ???

htmlspecialchars_decode() http://ca.php.net/manual/en/function.htmlspecialchars.php http://ca.php.net/manual/en/function.htmlspecialchars-decode.php

I take a one week break from PHP and look what happens. <?php include("./constants.php"); $stylesheet; // Set Variable for Later Use if(!file_exists("styles/style.txt")){ echo "<strong>An Error Has Occured: Cascading Style Sheet Setup File is Corrupt or missing.

I want it to get a proper URL for later use.

No, it is not a mid-term. I am in summer. I am trying to figure out how to use classes.
