For sanity reasons standards are needed. Here are a list of standards.

 1) <?php ?> PHP tags
 2) Don't break out of php tags
 3) Use echo primarly
 4) Use ' in all places possable for example echo 'boo'; \' to escape
 5) Arrays of variables are set with ' $var['demo'] = 'im cool';
 6) Indent with spaces and use \n line breaks (Don't use tab we don't all
     have huge monitors! If people are on a shell they can't see stuff
     past 80 columns!)
 7) Comment like a book and use only # comment lines so if needed
     things can be commented with /* */ and not get messed up
 8) Put "(edit start)" before the change(s) and "(edit stop)" at the
     end of each change so it's easier to see what you did
 9) Use functions that are default in windows and *nix packages of
     PHP (version 4) so everyone can use the code
10) Make a list of changes and the lines they start on
11) Don't bunch stuff up like statments or setting of variables
12) Include your name and e-mail so you can get credit for your edit or
     be asked questions if needed
13) No leet speek in comments or similar stuff.
14) Submit snippets they help everyone, not just you.
15) Don't send files in .zmdg.srg.dfr3.dngf95 format. Send them as
     plain text, not everyone has your program to open that file type
     and it should not be that people need to install programs just
     to read the file. (Others might not even be able to use the
     program needed to see the files on their Operating System.)

 # Demo of commented code
 echo 'i\'m standard code!';

  # infinate loop
  while (1) {

   # (edit start)
   # added echo of yay
   echo 'yay';
