count newlines in heredoc variable

[Adam Cantrell]

How could I count the number of newlines in a heredoc variable? This
outputs 0, but I thought heredoc preserved newlines?

<?
$test = <<<END
<a href="test5.php ">adam</a>
<p>
Hi There
</p>
END;

echo substr_count($t est, '\n');
?>

Re: count newlines in heredoc variable

Hi,

You're correct, but you just need double quotes: "\n".

In a single-quoted string, the only interpreted escape sequences are \
\ and \'.
