What will be the output of the following PHP code snippet?

<?php
echo <<<"FOOBAR"

Correct: Code will run successfully.

Explanation: Answer option A is correct.

PHP 5.3 allows Heredocs to use double quotes in string declarations. Hence, it is a valid code for PHP 5.3:

<?php

// Heredoc 
echo <<<"FOOBAR"
Hello World!
FOOBAR;

// Nowdoc 
echo <<<'FOOBAR'
Hello World!
FOOBAR;

?>
