Is the case of <?php important in any way?

From: Richard Quadling on 26 Apr 2010 04:51 Hi. I've recently come across some third party code which uses ... <?PHP as the PHP tag. This is the first time I've seen PHP in upper case for the tag. The code works in V5, so, from this, I can assume the tag is read case insensitive. Are there any issues with this when moving forward? When Unicode support is re-committed to trunk, does case sensitivity become part of this? Regards, Richard. -- ----- Richard Quadling "Standing on the shoulders of some very clever giants!"

Glance through some of the user notes on the site and you'll see that some folks prefer to use UPPER-CASE <?PHP as opposed to lower-case <?php. It's always worked just fine. In fact, I remember a PHP3 site that someone wrote (.phtml and .php3 files!) that used UPPER-CASE in every file, including for variables and functions. I don't remember having to modify that part to work (but thinking how much I'd love to break the person's CAPS LOCK off the keyboard permanently). > When Unicode support is re-committed to trunk, does case sensitivity > become part of this? From this, I gather you meant to send this to Internals, but still, I wouldn't anticipate any change in case-sensitivity regarding any part of the engine that hasn't yet required such. Opening tags, functions, operators, et cetera. User-defined things like variables will be case-sensitive, of course, but only the lamest of the lame would appreciate otherwise. ;-P -- </Daniel P.
