I'm using the fgets() function so I can read the file line by line and do the matches that I need to do and increment the counters as needed. Right now I have 3 loops looking for everything, which seems to me not to be the best way of doing this. I've also encountered that a line may have the file extension I want but it's actually the soucre of another file. (see below for example)

Save yourself a ton of work. Dump the raw logs into a db, and you can
do all the queries on the db. Something like this...

CREATE TABLE `rawLogs` (
`ipAddress` int(15) NOT NULL default '0',
`rfcIdentity` varchar(32) NOT NULL default '',
`apacheUser` varchar(32) NOT NULL default '',
`date` int(15) NOT NULL default '0',
`request` longtext NOT NULL,
`statusCode` varchar(32) NOT NULL default '',
`sizeBytes` int(11) NOT NULL default '0',
`referer` longtext NOT NULL,
`userAgent` longtext NOT NULL,
KEY `ipAddress` (`ipAddress`),
FULLTEXT KEY `search` (`request`,`referer`,`userAgent`)
