How can I exit with an error message in PHP/HTML?

I am checking if a particular value is set using isset. I want to exit the script and display an error message like "Name not found, Enter a valid name". Currently I am checking like this:

if ((! isset($_GET["name"])) or (! is_dir($_GET["name"])) or (empty($_GET["name"]))) {

    Print "Name not found, Enter a valid name"
}

After the print, I want to exit without further execution of code. How can I exit with the my error message and no default error message from PHP?

You would use the die or exit methods. This will halt all PHP and HTML from being displayed or executed.

Example: 

if ((! isset($_GET["name"])) or (! is_dir($_GET["name"])) or (empty($_GET["name"]))) {

    die("Name not found, Enter a valid name");
}

 die("Name not found, Enter a valid name");

That should help!
