I need to be able to pull the current <Title> tag from the header into
the body of the html page. We started coding this with php, and we
were able to get it working. However the entire page is being parsed
and really bogging down the system and the pages load very slowly.
(the system is Dual P4 2.4, 1GB ram, Redhat 9.0)
To fix this we decided to just use javascript, which worked great.
Text loaded immediately. However, search engines will not process the
javascript, thus this text will not be available in the document to be
scanned.
Does anyone have a way to pull a title tag from a document and display
its content as text only within a document, Without loading down the
system? When we tried it, it took the pages at least 5 times longer to
load than without the code.
Any feedback at all would be greatly appreciated. Thanks very much.

I'm not sure of your exact requirements but the easiest solutions seems to
use a variable:
<?
$title='Foo';
?>
<html>
<head>
<title><?=$title?></title>
</head>
<body>
<p>This page is "<?=$title?>".</p>
</body>
</html>

Can you describe the situation in greater details? Are you saying you have
many static HTML files that need adjustment, or are the pages generated
dynamically?
And what exactly do you mean by parsing the page? Finding a text string
within a file is absolute cakewalk. It shouldn't bog down the system to such
a degree.
WE have 1000s of static pages. We need to read the title from each
page and display that on the page.
We are using the following php function which causes extremely slow
page load times..
function get_title () {
$tempHost = $_SERVER['HTTP_HOST'];
$tempPath = $_SERVER['PHP_SELF'];
$tempQuery = $_SERVER['QUERY_STRING'];
$loc = "http://" . $tempHost . $tempPath . $tempQuery;
$open=fopen("$loc","r");
while(!feof($open))
{
$line=fgets($open,255);
$string = $line;
while ( ereg( '<title>([^<]*)</title>(.*)', $string, $regs ) )
{
$string = $regs[2];
}
}
return $regs[1];
}

Why!
We are using the following php function which causes extremely slow

If the pages are static you should create a static list with titles.
function get_title () {
$tempHost = $_SERVER['HTTP_HOST'];
$tempPath = $_SERVER['PHP_SELF'];
$tempQuery = $_SERVER['QUERY_STRING'];
$loc = "http://" . $tempHost . $tempPath . $tempQuery;

We need to pull that info and display it as text. We want to do it with
php if it is possible. I dont want to have to build a database for the
same info to pull it that way, there has to be an efficient way to do it
right on the page that isists as it is.
Thanks for your help.

The main problem here is that you're pulling the text through HTTP. You will
see significant improvement in your script by fopen()ing the file through
the file system.
Perhaps even more damaging to performance is the fact that you're calling
ereg() on each line of a file. ereg() known to be less efficient than PCRE.
And compiling a regular pression takes time.

If you need this there is something definitly flawwed in your setup...
but you can get the already generated output from a script with a ob
handler: http://nl3.php.net/manual/en/ref.outcontrol.php

If I understand well what you mean, you are trying to get a pretty
static TOC html page. Why don't you just implement some very basic
caching system? (No rocket science implied, really).
Basically, you keep the same script, but crontab it (or use this
windows scheduler thing if you are running Windows), every hour, or
every day, every 10 minutes, depending of how often the <title>'s are
changed.
With some basic modifications, the script, instead of generating the
page on the fly, will generate a static .html page whose speed can't
be beaten.
Or am I misunderstanding something?

It seems that my original reply got lost somewhere... the main problem is
not ereg, but the fact that he is not terminating the WHILE loops after the
<title> tag is found. Inserting a BREAK 2; into the inner WHILE loop after
$string = $regs[2]; will fix the big problem. That and a fclose($open); at
the end wouldn't hurt either.
