Incorrect. I used to think that, but was corrected by a kindly member of the PHP development team. If you take a good look at the HTML 4.0 specification, the "name" attribute is defined as CDATA, which basically means it can contain any character. > and yet this seems > to be the only > way to get a set of form elements grouped into an array for > server side > processing. > > Why doesnt PHP do (Perl/ASP) automatically create an array > when there is > more than one form element with the same name in the post/get data? So that there will be no uncertainty over whether a particular named element will be an array or a scalar, thus avoiding the need to spatter is_array() tests (or (array) casts) all over the place. However, the HTML 4.0 spec also says of name that "This attribute has been included for backwards compatibility. Applications should use the id attribute to identify elements", and the id attribute *is* restricted as you mention -- so perhaps this is still an issue to be resolved in the future. (I haven't checked what the XHTML spec says!) Cheers!
