PHP heredoc不接受换行

Question

I got a mystery when I tried to test a heredoc construct in PHP. I can not figure out what is a problem with this code:

<?php
$author = "Scott Adams";
$out = <<<_END
Normal people believe that if it ain't broke, don't fix it.      
Engineers believe that if it ain't broke, it doesn't have enough
features yet.
- $author.
_END;

echo  $out;
?>

According to my book here is not necessary to use the to put a linefeed, just type an enter button. But it does not take linefeed just print the text and that is it. Do I have problem with my apache server or May it be misconfigured? I am using it with the default settings.

Thanks for the help.

In the browsers all white-space (tabs, new-lines, multiple spaces) is collapsed.

If you want to show new-lines in the browser, you need to add html line-breaks:

echo nl2br($out);
