Parallel Processing in PHP

Hi,

I want to perform Parallel Processing in PHP. Let me try to explain my problem.
I want to open 2 files with fopen at the same time.

For Example first file takes 30 seconds and 30 seconds seond file to read in web.
and total time will be 60 seconds.
Can i read both files in 30 seconds with parallel execuation?

<?php

$handle_1 = fopen("www.domain.com/index.php", "r");
$text_1 = fread($handle_1,filesize("$handle_1"));
fclose($handle_1);

$handle_2 = fopen("www.domain.com/index.php", "r");
$text_2 = fread($handle_2,filesize("$handle_2"));
fclose($handle_2);

$text = $text_1 . $text_2;

print $text;

?>

As above code run line by line and takes much time. Is there any way that i can open both or more files Simultaneous ?
How can i execute some my code in parallel processing?
