Reading large files via PHP?

["Jay Paulson \(CE CEN\)" <Jay.Paulson@xxxxxxxxxxxxxx>]

I'm reading in a 66MB file into php so I can parse it and load it into a database.  However, it is taking a long time for php to read the file.  So long that the script times out.  I know about the ini_set("max_execution_time", 120) or whatever length I want to set the time out for the script, but my question is as follows.

Is it possible to read in a file and at the same time echo out a status of how far along the file has been read?

The code I have right now is below.  Just wondering if what I'm trying to do is possible and how to do it.

// set script timeout
ini_set("max_execution_time", 120);

// import file name
$log_file_name = "access_log.1";
echo "Reading access log!<br/>";
if (!$ac_arr = file("./$log_file_name")) {
	echo "Couldn't load access log!";
	die;
}

Thanks!
