Hello,
I have a function that uses tidy to attempt to clean up a bunch of crappy HTML
that I inherited. In order to use tidy, I write the crappy HTML to a temporary
file on disk, run tidy, and extract and return the clean(er) HTML. The program
itself works fine but with all of the disk access, it runs quite slowly. I saw
on this page (http://www.php.net/manual/en/wrappers.php.php) that I could write
to memory by using php://memory. Unfortunately, I could not quite get it to
work. The problem is that in the below function, the code within the [[[if
(file_exists($dirty_file_path))]]] does not get run if I change
[[[$dirty_file_path]]] to "php://memory". Has anyone ever successfully used
php://memory before? If so, what can I do to use it in my code? Thank you.

function cleanUpHtml($dirty_html, $enclose_text=true) {
$parent_dir = "/filesWrittenFromPHP/";
$now = time();
$random = rand();
//save dirty html to a file so tidy can process it
$dirty_file_path = $parent_dir . "dirty" . $now . "-" . $random .
".txt";
$dirty_handle = fopen($dirty_file_path, "w");
fwrite($dirty_handle, $dirty_html);
fclose($dirty_handle);
$cleaned_html = "";

--char-encoding utf8 --drop-proprietary-attributes yes --fix-uri yes " .
($enclose_text ? "--enclose-text yes " : "") . $dirty_file_path . " 2>
/dev/null");
$tidied_html = file_get_contents($dirty_file_path);
$start = strpos($tidied_html, "<body>") + 6;
$end = strpos($tidied_html, "</body>") - 1;
$cleaned_html = trim(substr($tidied_html, $start, ($end -
$start)));
}
unlink($dirty_file_path);
return $cleaned_html;
}
