Linux and PHP

[kardon33]

Ok ill give you a quick idea of what i am trying to accomplish. I have a script that sends a command to the server (linux) to play a playlist of audio files, the playlist is just an array with the song names in it. When i play a song i need to record the PID # of the operation so if i have to kill it i can. And it also has to record how long the song was playing for.

The Problem is that when i run the script it plays the way i want to to but it does not update my db with the songs PID until after it is done.

Heres my code so far:

function set_var($name, $val) {
	$dbhandle = new PDO('sqlite:../../data/intel.db');
	$dbhandle->exec("UPDATE vars SET value = '$val' WHERE name = '$name'");
	return get_vars($dbhandle);
}    

 set_var('php_pid' , $php_pid );   

 $php_pid =  getmypid(); // Gets the php script pid  I also need that.
 
 set_var('php_pid' , $php_pid );   

print "Php Script is running with PID - $php_pid<br>";
$songs = array ('PhilCollins.mp3');

function madplayer ( $songs )
{
  foreach ($songs as $song)
  {
    $song_time = 0;
    $start_time = get_computer_time(); 
    set_var ('last_played' , $song );
    
    
    set_var( 'mp_pid' , system ("madplay -m /mnt/cf/music/$song & echo \$!" ));
    
    print $pid;
    #set_var ('mp_pid' , $pid );
    
     print "<hr>"; 
     print "Pid -- $pid";
     print "<hr>";

    $song_time = calc_timeString ( get_computer_time() - $start_time );
      
    set_var( 'song_time' , $song_time  );   
    set_log( " song_time -- $song_time " );

  }
}
