How could I count the number of newlines in a heredoc variable? This
outputs 0, but I thought heredoc preserved newlines?
<?
$test = <<<END
<a href="test5.php">adam</a>
<p>
Hi There
</p>
END;
echo substr_count($test, '\n');
?> 2  1636 
Hi,
You're correct, but you just need double quotes: "\n".
In a single-quoted string, the only interpreted escape sequences are \
\ and \'.
Regards,
John Peters
