[PHP] Re: Custom Open Tags

[Sven Schwyn]

Hi all
Thanks for your hints. I need this feature for an easy to use 
minimalistic CMS solution, so tweaking the PHP source is not that much 
of an option. But evals do the trick of course. I ruled that out at 
first because I thought it'll cause a lot of clumsy code. Yet there's 
quite an elegant way to do it, I mail it for future reference:

/**
 * Includes a file executing ?mc ... ? tags as if they were ?php ... 
? tags.
 *
 * @param string $file file to include
 * @param bool $php whether to execute ?php ... ? tags as well
 */
function xinclude($file, $php=TRUE) {
$content = file_get_contents($file);
if (!$php) { $content = preg_replace('/\?php.*?\?/', '', 
$content); }
$content = str_replace(\x3Fmc, \x3Fphp, $content);
$content = print '.str_replace(array(\x3Fphp, \x3F), 
array('; , ; print '), $content).';;
eval($content);
}

The only downside: No single quote (') is possible outside ?xyz ... ? 
tags in the file included. This can of course be fixed, but only with a 
ridiculous amount of code. If only there was a way to do heredoc 
strings that DON'T parse variables (like in Perl).

[PHP] Custom Open Tags

[Sven Schwyn]

Hi folks
Does anybody know whether there's a way to tell PHP to accept an 
alternative open tag like for instance ?mytag or ?mc along with the 
normal ?php tag?

I'm looking for a way to have two kinds of PHP code in a page. The 
first kind tagged ?mc ... ? contains the PHP code to manage page 
elements (like includes, menus etc) while the second kind tagged ?php 
... ? contains normal PHP code for dynamic pages (like DB stuff). A 
page resides on the Staging (Virtual) Host and contains both kind of 
tags. When viewing the page on the Staging Host, both open tags are 
executed. Yet when publishing a page to the Production (Virtual) Host, 
the mc-tags are executed (and thus complete the page design) while the 
php-tags are left untouched (as they contain the dynamic stuff). Sounds 
more complicated than it is :-)

Thanks for your hints,-sven

Hi Trevor
I'm not sure, but that may allow you to use ?php ? AND % % tags at
the same time.
Thought about that, it would actually be very elegant if it was the 
other way round. ASP tags would be great instead of a ?mc ... ? 
custom tag, however, that won't do the trick as the execution of the 
?php ... ? tags can't be switched off (or can it?) when using % ... 
% tags.

Thanks for your thoughts though! -sven
