return javascript code full of 's, "s and \s from within a class, how can I do it?

Question

I have a very long javascript (so long that it's too long to escape manually every single problematic character) that I need to return from a method inside a class. Are there way to return (return not echo or print) safely this kind of code?

Thank you very much

I think you're after HEREDOC syntax or output buffering:

$str = <<<EOD

function javascript() { alert("foo"); }

EOD;

// or

ob_start();
?>
function javascript() { alert("foo"); }
<?php
$str = ob_get_clean();
