Paralel Process In PHP
In my own experience, paralelizing process in PHP is alot efficient. Not saving your time, but it will save memory usage.
I use paralel method when working with several task at once. For example, fetching several RSS feeds. Let’s give it a try.
Sample case, we must fetch data from 5 (five) rss feeds.
// call this run.php
$feeds = array(
"http://feeds.com/feed1.xml",
"http://feeds.com/feed2.xml",
"http://feeds.com/feed3.xml",
"http://feeds.com/feed4.xml",
"http://feeds.com/feed5.xml"
);
foreach($feeds as $feed){
exec("php.exe fetcher.php?url=$feed");
}
?>
Well, that’s jus’t a simple illustration. Not so good, I think 
I’ve written more complex task using paralel method for my web crawler and it works as beast!
