title: Create a log file in PHP
body: <p><br>
  So, I have an application in PHP that register users and items and then I can "give" an item to a user, and what I want it to create a log file that register the 'life cycle' of an item.
  eg:<br>
  I create an item and give that item to the user 'Mike', a few weeks later the user 'Mike' give back that item bc the item broked, and I want all that to be on a log file.
  <br>Any tips? Thanks!</p>
