Okay, if I understand everything correctly, something like this may work, if
you can get around the issue of your file sizes being so large, and you can
deal with the amount of memory this is going to eat up, and you realize that
Perl is probably better suited to the job...
//read numbers
$numbers = file("in.txt");
//read all lines from log file
$fp = fopen("file.log","r");
$log_file = fread($fp,filesize("file.log"));
//match lines of log_file that start with 'code'
//and match number
preg_match_all("/^(code.*number=([0-9]+).*)$/m",$log_file,$matches);
//put matches into an array such as
// $array[code] = number
$x=0;
foreach($mathes[1] as $code)
{
$number = $matches[2][$x++];
$log_file_array[$code] = $number;
}
//compute intersection of log file array
//and numbers array
$intersect = array_intersect($log_file_array,$numbers);
//flip the log array, so you now have
//an array full of the lines in the log
//file that matches a number in the in.txt file
$answer = array_flip($intersect);
Hope that works... I can't test it. There are many ways you can do this...
