Re: Checking a strings case

I think the difference between lower case and upper case (in terms of ascii characters) is consistantly 32. That's to say to get from 'a' to 'A', you have to add 32 to the ascii number representing 'a' to get 'A'. I'm not sure how this translates binarily (or any other way), and to what extent this brainstorm exercise helped you any. What code did you use to solve the 'non-interlaced' use of caps and lowercase text? -----Original Message----- From: ODCS <odcs@rogers.com> To: PHP General <php-general@lists.php.net> Date: Tuesday, April 15, 2003 12:54 AM Subject: [PHP] Checking a strings case >I'm trying to create a function to check a users input for "foul" language >and want to be able to check variations of case (i.e. CasE or cAsE).
