Subject: Re: [nycphp-talk] Creating multidimensional arrays


I'm not sure how compliant this is to HTML specifications, but one
useful thing you can do is use arrays in form variables, for instance:

<input type="text" name="array[test]" value="">

When you post this, $_POST['array'] will be a populated array. I have
found this useful when you have some sort of multiple select. You can
have 15 check boxes with the name="option[<some unique id
here>]" and then you just get an array of all of the select options to
loop through.

I'm not sure if this would speed anything up (it may make it even make
it a bit slower) but it does provide a small amount of convenience.
