Multiple "threaded" processes?

Hi,
Is it possible to run 10 or 20 functions at the same time in php?. In windows development we would create threads, is this a feature of php or am I barking up the wrong tree? lol

I basically have a function (or 2 ) I call that returns parsed html and depending on which page it is looking at it can take some time. So, what I want to do is say, OK I need to parse these 20 pages lets parse all 20 at the same time and wait until all 20 processes have finished then publish, post or process the overall results.

Any help appreciated.

Check out http://www.php.net/manual/en/ref.pcntl.php , to see if you can find an answer to your question there.

PHP AFAIK cannot support multiple threads, and they don't recommend using multiple processes in a web server enviornment.

I think you'll just have to find a faster way to work.

Can we see the code you are currently using?

Hi aolXFT,
Its the same code you provided to me last night!!! re search engine parsing. I have split it up as a test script but basically it would be great if I could parse all 15 or so search engines at once. ie the Do_Google and Do_Alltheweb etc

<?php

$words            = "key words to search for";
$my_url            = "domainnametofind.com";
$html            = "";
$loc_tag            = "";

$page = $page. page_header();

do_google();
do_alltheweb();
//List other 15 or so


$page = $page.page_footer();

echo $page;
exit;


/*============================================================================*/
function page_header()
{
global $words, $my_url;
$tmp = '<table width="52%" border="0" cellpadding="0" cellspacing="1" bgcolor="#000033">
  <tr>
    <td align="center">
      <table width="100%" border="1" cellpadding="0" cellspacing="0" bordercolor="#FFFFFF" bgcolor="#CCCCFF">
        <tr>

        </tr>
        <tr>
          <td bgcolor="#FFFFCC"><font color="#999999" size="2" face="Verdana, Arial, Helvetica, sans-serif">'.$words.'</font></td>
        </tr>
