Run php process in background

[Ortix]

Hey guys, I've hit a huge obstacle in my coding process of a script I am writing.

 

It is basically an uploading interface script and it works like this. I have files on my server and I want a user to click a button which fires a php script which in turn fires a bash script which IN TURN fires the uploading program (plowshare).

 

So to make it simple: user logs in, sees upload button. Clicks it, file starts uploading. I then want the user to see "upload initiated" and that's it. The problem is that with what I have now, the script just won't finish loading until the file has been uploaded and as a matter of fact I don't even think it is uploading anything :S

 

Here are the scripts:

 

PHP interface to call the bash script:

<?php

error_reporting(E_ALL);

function run_in_background($Command, $Priority = 0) {
if ($Priority)
$PID = shell_exec("nohup nice -n $Priority $Command 2> /dev/null & echo $!");
else
$PID = shell_exec("nohup $Command 2> /dev/null & echo $!");
return($PID);
}

function is_process_running($PID) {
exec("ps $PID", $ProcessState);
return(count($ProcessState) >= 2);
}

$file = $_GET['file'];
// Location of file relative to the index
$where = $_GET['where'];
// Absolute index location
$absolute = '/var/www/vhosts/animekyun.com/httpdocs/icarus/';
$where = $absolute . $where;
//$outfile ='log';
echo $where . $file . '<br>';

echo "<h2>The upload has been initiated!</h2>";

$ps = run_in_background("/bin/sh uploadparser.sh $file $where > $outfile");
while(is_process_running($ps))
//echo $output;
?>

 

Bash script to call uploading program:

#!/bin/sh
{
FILE=$1
WHERE=$2
FILENAME="/var/www/vhosts/animekyun.com/httpdocs/icarus/debug/debug_mu_$FILE"
FILENAME2="/var/www/vhosts/animekyun.com/httpdocs/icarus/debug/debug_multi_$FILE"
/usr/local/bin/plowup megaupload "$WHERE$FILE" >> "$FILENAME".txt 2>&1
/usr/local/bin/plowup multiupload "$WHERE$FILE" >> "$FILENAME2".txt 2>&1
} &

 

this works fine when I pass the variables as arguments in CLI

 

I hope i have been clear enough, it does seem rather confusing
