+## Die and Exit
+
+The `die()` and `exit()` functions are identical. They each take one argument (a string) containing an error message. Upon being run they output the message and immediately halt execution of the script.
+
+```PHP
+<?php
+die('Die() function was run');
+```
+```PHP
+<?php
+exit('Exit() function was run');
+```
