[Phpmyadmin-devel] structure diff - possible patch

Hi everyone,

Some of you might remember I asked for a structure diff earlier, I want 
to compare 2 tables and get an alter query which would make the target 
table to look exactly like the original table.

I have now made a small hack which almost does this, at least it show 
the idea of what I want it to be.

I added the file diff_tables.php which currently takes ?db as an get 
argument. It shows the table in that database and you can pick 2 tables 
to compare and you get a hopefully working alter query. :)

I modified left.php to show a link after the num_tables, like (diff) 
which goes to diff_tables.php with ?db as the database.

If you want to try it out, patch your 2.3.2 version of phpmyadmin with 
the files, or visit http://www.egp.cx/phpMyAdmin-2.3.2/ where I put up a 
patched version. Please dont destroy the tables to much. :)

Some ideas of what to improve:
  * maintain the order of the fields
  * maintain keys/indexes and auto_increment fields
  * make it possible to diff tables between databases
  * make it possible to diff create table queries
  * create a nice graphical view over whats added/changed/dropped

Do you have any furhter suggestions?

Please comment and try it out and think about it. The code is still very 
hacky, and I might have re-invented the wheel in some places, but I'm 
not yet familiar with all libraryfiles etc.

Best regards,
