Your second test script look bogus to me.

Have you considered using http://www.php.net/manual/en/ref.exec.php,
which gives the lines as an array anyway?

How big is the logfile?  Do you have magic_quotes enabled?
If you leave it running, how long does it take to complete and how much
memory does it use?

split hangs for some reason, but doing the same logical process with
other functions returns a very quick result.

The problem is that I'm trying to process the mysqlbinlog output and
parse it for easier management. The logical process is as follows.

$sys = `mysqlbinlog logfile`;

This part works fine, but when I try:

$lstk = split("\n", $sys);

the script hangs for well over 5 minutes (I kill the script at that
time. However this code produces the desired results in less than 2
seconds:

 $mybin     = "/usr/local/mysql/bin/mysqlbinlog";
 $mylogpath = "/var/lib/mysql/";

 $dolog = $mylogpath."towely-bin.010";

 $tmpfname = tempnam ("/tmp", "mybinlogger");   
 $fp = fopen($fp, $tmpfname);
 fwrite($fp, `$mybin $dolog`);
 fclose($fp);
 
 $lstk = file($tmpfname);
 unset($tmpfname);
 print count($lstk)."\n";

I am using this from the command line version of php 4.3.2 RC1. Here is
my php -v:
