Re: Anyone have a tool/script to convert <? to <?php (but not <?=)

Do you have a _full_ specification of your requirements? Every time someone has offered a solution so far, you have come back with a new requirement, and those are currently scattered through the various postings. If you start a new, but similarly named thread, with a complete list of cases, the solutions can attempt to address that, and the next person who trying to solve a similar problem will have a more compact reference.

No I don’t want to change <?

?> To <?php if ($foo) ?> That's ugly. And loses any block/indentations which help in readability. What I want is to ONLY add a space in the case there is '<?command' so it becomes '<?php command' and not breaking it with '<?phpcommand' ... adding a space all the time makes other formatting ugly then as '<? command' becomes '<? command' with two spaces. I realize this may seem trivially cosmetic; I was just asking if that lookahead stuff can be applied to the replace portion as well somehow? Or maybe I run two separate regex matches on the parsed file to handle both cases since I intend to write a little .php script that will traverse a directory recursively to hit all the *.php files and re-write them (once this is tested of course)

That one matches great too! Now it’s the replacement part that’s the sticky one. I could always substitute with “<?php “ (with space) but that’s ugly. I only need to add a space in the case of <?command Also what tool are you using there?

Not sure why you are saying that spaces are irrelevant thou. On Fri, Feb 14, 2014 at 1:34 PM, Daevid Vincent <daevid@daevid.com> wrote:

*sigh* <?=$foo?> is perfectly valid so is <?=$foo;?> or any combination WITH SPACES OR NOT. If this were trivial, I wouldn't have asked the list. I've been coding PHP since 1996. ;-) So if you have <? you have to make sure it doesn't have a '=' after the '?' to convert to '<?php' Spaces are irrelevant and can NOT be relied upon as a unique feature.

Related, for extra credit it drives me bonkers to see this: Hello <?= $username; ?> Note the end semicolon on the variable. I'd want to strip all those off
