Stopping PHP Script Execution

Do you know all the ways of stopping PHP script execution? Put your knowledge to a test with this question from the Zend PHP 5 Certification Mock Exam.

The question is as follows. Correct answers in bold.

What would go in place of ?????? below to make this script execute without a fatal error?

<?php

$a = 1;
$b = 0;

??????

$c = $a / $b;
?>

• quit();
• die();
• stop();
• __halt_compiler();
• exit();

die() and exit() are quite obvious, stop() and quit() do not exist and what about __halt_compiler()? The latter was introduces in PHP5. Manual page says it stops the execution of the compiler and nothing after this call is executed.
