My PHP , Wordpress and Linux Lab

Ok the title is a bit mis-leading , but well there was a point where i had to run alot of PHP processes simultaneously and use the servers resources to the fullest. For instance if you are making a cralwer or something and find that its too slow processing a page and then moving on to the next. You can use this approach.

for($i = 1 ; $i < 10 ; $i++){
$param1 = “anything”;
$param2 = $i;

exec(”pkill -f ‘runone.php $param1 $param2′”);
exec(”/usr/local/bin/php /home/abc/public_html/runone.php $param1 $param2 > /dev/null &”);
}

What this will do is , first kill the process if it already exists in the background and then tell linux to execute PHP from command prompt with the script path as parameter , then $param1 and $param2 can be the parameters you pass to that script , because remember that PHP from shell CAN NOT take parameters from query string.

So $param1 and $param2 will be received in runone.php like this..
$param1 = $argv[1];
$param2 = $argv[2];

Hope this helps someone!
