You can use the CURL module, which has support for timeout.

Threre seems no easy solution for this job.
The best bet could be to write up do-it-your-self B-tree
implementation in PHP...
I have not been following this thread, so please excuse my post if
this has been covered or if I'm off-base, but why not just use MySQL?
While I have not written a B-Tree, I have written a binary tree -- if
you have a Mac you can review the demo and documentation here:
http://sperling.com/freeware.php
-- and that was not a small task, at least for me. I used a splay to
keep in balanced and current.
So before I would venture out and rewrite that for php, I would
exhaust all possibilities of using MySQL first.
Cheers,
tedd

yes, you could write a program in c and call it via the shell from within
php.
say you had a program findPrefixes, and it takes as an argument a file
containing the
dictionary to search and it spits out a filename of the matches (which it
creates).
there would be several optionsto call it from within php.
i would use the backticks; something like this:
$matchFile = `findPrefixes $dictionaryFile`;
$matches = file($matchFlie);
if you write it in c the chances of beating out the perl script are good.
also, if youre considering a database solution (rdbms), i recommend
sqlite3. its not
nearly as heavy as a server based solution.

I have also tried to enable Multibyte string feature,
and tried the following :
echo mb_strtolower ( 'Ô' ) . '<br>';
But it still gives me a weird character.
My page is also UTF-8 encoded.

Nevermind, didn't see second param of mb_strtolower function which let you
specify encoding type.

I am having a issue parsing an html file.
I want to pull all the data between two html tags.
Problem I am having is that no matter what I try I can pull either tag or
both but not the data in between.
<div class="record" id="one">
<div class="rideon">
<h2>
<span>Welcome to
Rideon</span>
</h2>
</div>
</div>
</div class="record" id="one">
function datamatch($document)
{
preg_match_all('/<div class="record" [^<>]*>(.*)/<\/div
class="record" [^<>]*>/i',$document,$elements);
$match = implode("\r\n",$elements[0]);
return $match;
}
This should return the following
<div class="record" id="one">
<div class="rideon">
<h2>
<span>Welcome to
Rideon</span>
</h2>
</div>
</div>
</div class="record" id="one">

You may want to try escaping your quotations. That could cause some issues.

Hi There
I am totally new to PHP and have just tried installing it on my machine
according to instructions on the php.net manual installation instructions
page - http://www.php.net/manual/en/install.windows.manual.php
I think I managed to do most steps but I have a few questions:
Under the PHP file, I have icons for php, php-win and php-cgi. If I double
click on any one of them, it says - "Are you sure you want to run this
software?" I have Windows Vista - 32 bit operating system and have
installed IIS7. Which one would you recommend that I run? Then, how do I
know that everything is installed properly?
Under optional steps:
How do I change the doc_root to point to the web servers document_root??
This was an optional step but not sure how to do this? (sorry basic
question!) and what extensions would you recommend that I install?
I look forward to any advice!
Many Thanks
Louise
