I tried modifying it in favor of better readability:

My attempt at a better format:

If you still have this problem, the issues are:

  1. %t already includes the square brackes ([ and ]);
  2. There is an extra \ before "%{User-Agent}i";
  3. The % before { is missing from "{X-Forwarded-For}i";
  4. By a limitation on how the parser was implemented, the library is looking for only one - when you're defining headers, so X-Forwarded-For will not work, but XForwarded-For will.

So your setFormat should be:

$parser->setFormat('%a - %u %t "%v" "%r" %>s %O "%{Referer}i" "%{User-Agent}i" "%{XForwarded-For}i"');

Which will yield:

  int(1591804006)
