Take the 2-minute tour ×  I am going to improve a web site in
Apache and PHP which has a page with a table containing a list
of files. My goal is to allow the user to set one of those files
as the “important” one based on some specific and subjective
criteria. In order to do that, I want to store the information
regarding the most “important” file in some way, with the
restriction that I am able to use neither databases nor files
(constraints imposed by supervisor).  My questions are:    • Is
it possible?   • How can I do this?  I already did a search in
this site, but I did not find an answer.  EDIT: By the way,
finally I solved my problem using an XML file. Thanks a lot to
everyone.  share|improve this question Your supervisor is an
idiot if he expects you to persist data without actually saving
it anywhere. –  Martin Bean Jul 26 '13 at 8:25 Please make sure
you make your supervisor read the above comment –  Mr. Alien Jul
