Ive built only a few forms mainly because the sites Ive done havent required much user input.

Im learning PHP/mySQL and am needing to be clear on the differences between some of the form actions...

Mainly Post and Get. Can anyone clerify what the difference between the two are?
And if you know of any other methods ill need to be clear on when learning PHP/mySQL interaction, I would really appreciate that info too.

Thank you
