is there a quick way to compare the results from two arrays and note the differences?
I have two identical tables in MySql (backup and current table) and I want to work out the differences between them (i.e. what fields are different). I could construct some long function, but I was wondering if anyone had a quick method (I am just learning PHP). Thank you - Nicolaas

That's an RTFM, see http://www.php.net/manual/en/ref.array.php for all the array functions. > I have two identical tables in MySql (backup and current table) and I want to work out the differences between them (i.e. what > fields are different).

Differences in database tables should be computed by the database itself if possible. BTW set your width to something beneath 80 to keep you articles readable.

It's tenuous in comp.lang.php since you haven't mentioned PHP...] If you have the data in an array, then: http://uk2.php.net/array_diff But if you're comparing data, I particularly like the Perl Algorithm::Diff module. http://search.cpan.org/~tyemq/Algori...orithm/Diff.pm Try comp.lang.perl.misc or comp.lang.perl.modules if you like the look of that. -- Andy Hassall / <andy@andyh.co.uk> / <http://www.andyh.co.uk> <http://www.andyhsoftware.co.uk/space> Space: disk usage analysis tool
