Why isn't this EOF javascript code appearing in the html when it is echoed?

In this php code I use the heredoc EOF to insert some javascript:

        $room= <<<EOF
<script type="text/javascript" charset="utf-8">
test;
            </script>
EOF;

when I try to echo $room it doesn't appear:

echo "<li style=\"text-align: center;\"><img src=\"example.com\" width=\"264\" height=\"198\" alt=\"\" /> $room</li>";

($room doesn't appear in the html).

however if I do the same with:

$room= <<&开发者_开发问答lt;EOF
test;
EOF;

Then the word test gets echoed in my list html element.

EDIT - to clarify, nothing appears in the source of the html when I do the first echo attempt (the list appears, but no script tags or test inside it).

<script type="text/javascript" charset="utf-8">
  test;
</script>

basically means nothing to javascript. I'd guess you want (in a sense of outputting anything at least):

<script type="text/javascript" charset="utf-8">
  document.write('test');
</script>

If you literally want to display the script tag, try:

echo '<li style="text-align: center;"><img src="example.com" width="264" height="198" alt="" />', htmlspecialchars($room), '</li>';
