Just a follow-up on this, the problem was 'Fatal error: Allowed memory

After some nice help, I found that this is actually a common problem
with intense regexes in php. Quick fix is using ini_set() to increase
your memory_limit to something massive, like '400M'. This gives your
script access to that much memory for its life-time. If you have this
problem, then you probably also have to do this
set_time_limit(0); //remove any max execution time

PS - for anyone confused, here was the script . . . i didnt think it was
that confusing, sorry guys!
function parse_access($file_name)
{
// read file data into variable
$fh = fopen($file_name, 'r') or die("cant open file for reading");
$theData = fread($fh, filesize($file_name));
fclose($fh);
// perform regex
$regex = '!(\d{0,3}\.\d{0,3}\.\d{0,3}\.\d{0,3}) - -
\[(\d{2})/(Jan|Feb|Mar|Apr|May|Jun|Jul|Aug|Sep|Aug|Oct|Nov|Dec)/(\d{4}):(\d{2}):(\d{2}):(\d{2})
-\d+] {1,4}"GET ([._0-9\-%a-zA-Z/,?=]+) ([.0-9a-zA-Z%/\-,_?]+)" (\d{3})
(\d+) \[(.+?)] \[(.+?)] \[(.+?)] (\d+) (\d+) (\d+) (\d+) (\d+) (\d+)!';
//echo $regex . '<br><br><hr><br>';
$num = preg_match_all($regex, $theData, $match, PREG_SET_ORDER);
//echo "after regex - we are still alive!";
//go on to do some boring stuff, like write this to an array, perform
stuff, graph stuff, blah blah
}
Can you also post a few lines from your access log so we've got
something to test against.
The regex looks incorrect to me in a few places:
-\d+] {1,4}
for example.
How to debug your script:
make a copy of the log file and trim it down to say 20 lines; run the
script on it to verify it's doing what you want it to.
check the size of the "real" log file, then multiply it by 2.5 and see
if the total is greater than your php max memory setting. (exp: $theData
will hold the full file, matches will also hold another copy of most of
the file, then a bit extra for php to use)
