Even if you get around the execution time the above code is going to use
up 66megs of memory to store that file in $ac_arr.
You'd be much better off doing something like:
$fd = fopen("./$log_file_name", "r");
while ( !feof($fd) ) {
$buf = fread($fd, 32768);
// process buffer here
}
fclose($fd);
That will let you do your progress thing as well as not eat up so much
memory. Play around with values of 32768 to see if smaller or larger
makes any different on your system.
Good luck!
