Couple Options:
Change your script to accept a single filename from the command line
($argv) and then run several of that script from command line in the
background:
php -q singlefileprocess.php datafile1.txt &
php -q singlefileprocess.php datafile2.txt &
php -q singlefileprocess.php datafile3.txt &
http://php.net/pcntl
This basically would be the same (sort of) as just running multiple
copies of your PHP script, one for each file, but keeps your script
able to process multiple files...
Not sure it's worth the effort, but there it is.
You could also use http://php.net/exec to have PHP fire up more PHP
scripts in the background:
<?php
//loop through $filename
exec("/full/path/to/php -q processonefile.php $filename &", $output,
$error);
if ($error) echo "OS Error: $error\n";
echo implode("", $output);
if ($error) exit;
?>
Note that in all cases, not only with the results most likely not
return to the main file, they'll be reading the files in parallel and
doing whatever to them... Be sure that this won't affect other parts
of the application.
