Re: Retrieving array_keys from $_POST

I went home last night and laid in the bead with my trust lappie, and I wrote a very similiar snipit just like you wrote, I love PHP. Coming from a harden perl background, this is just incredible. What makes this so cool, is the php program doesnt care if you add more fields to your form, it just gets them and from their you can process the information and store them, or whatever... Do you think its a good idea to use SQL statements in an array ? I was thinking of creating an array with all the SQL statements that I would need and just calling the elements. That way it makes the code more uniform and easy to update if needed. Rather than editing multiple lines of code, you basically edit one array...
