RE: [PHP] Variables don't pass... *sniff*

[snip] To maintain absolute compatibility, just use $HTTP_GET_VARS. It's availalable in all PHP versions, just deprectaed in versions here $_GET is available. [/snip] Just to be perfectly clear on this. Let's say that I am writing an application that I am going to release to the public (for free of course!). In order that the application be as compatible with the many installed versions of PHP as possible I should always use $HTTP_GET_VARS or $HTTP_POST_VARS ? Or is there a point at which the formation of the variable call changes (like the $_GET and $_POST in the latest versions)? If there is a point at which it changes how can I account for that in code, other than telling the potential use that "you must be running PHP 4.x.x"? Thanks! Jay
