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

Question

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?

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

That should help!

@user1988876 this piece of code is supposed to show Name not found, Enter a valid name in the browser.

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");
}
