Web server access Log Parser

Install

Using composer:

php composer.phar require kassner/apache-log-parser:dev-master

Usage

Simply instantiate the class :

$parser = new \Kassner\ApacheLogParser\ApacheLogParser();

And then parse the lines of your access log file :

$lines = file('/var/log/apache2/access.log', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
foreach ($lines as $line) {
    $entry = $parser->parse($line);
}

Where $entry object will hold all data parsed.

stdClass Object
(
    [host] => 193.191.216.76
    [logname] => -
    [user] => www-data
    [stamp] => 1390794676
    [time] => 27/Jan/2014:04:51:16 +0100
    [request] => GET /wp-content/uploads/2013/11/whatever.jpg HTTP/1.1
    [status] => 200
    [responseBytes] => 58678
)

You may customize the log format (by default it matches the Apache common log format)

# default Nginx format :
$parser->setFormat('%h %l %u %t "%r" %>s %O "%{Referer}i" \"%{User-Agent}i"');
