Probably getting a little off-topic here but after I saw how seemingly
easy this might be, I had to give it a shot. I added this in
Zend/zend_language_scanner.l file just under the similar ?php block:
INITIAL?new([ \t]|{NEWLINE}) {
zendlval-value.str.val = yytext; /* no copying - intentional */
zendlval-value.str.len = yyleng;
zendlval-type = IS_STRING;
HANDLE_NEWLINE(yytext[yyleng-1]);
BEGIN(ST_IN_SCRIPTING);
return T_OPEN_TAG;
}
My vanilla ./configure ends with no errors, but when I compile it it dies with:
sapi/cgi/cgi_main.o(.text+0x1499): In function `main':
/home/greg/php-5.0.2/sapi/cgi/cgi_main.c:1580: undefined reference to

sapi/cgi/cgi_main.o(.text+0x150b):/home/greg/php-5.0.2/sapi/cgi/cgi_main.c:1591:
undefined reference to `open_file_for_scanning'
collect2: ld returned 1 exit status
make: *** [sapi/cgi/php] Error 1
I'm using PHP 5.02 source on a Debian sarge box.

RE: [PHP] Custom Open Tags
I think there's a way to redefine what tag PHP uses, but I think it globally resets it. I don't think you can say use !blah ! and also use ?php ?. I think that setting is in PHP.INI somewhere. It might be easier to change your to be executed later php tags to something else and before it's sent to it's final destination, do a string replace to change the tags. If you have two different servers, you might go into PHP.INI and set the following tag on the last server and turn it OFF on the first server: ; Allow ASP-style % % tags. asp_tags = Off I'm not sure, but that may allow you to use ?php ? AND % % tags at the same time. All in all, I think I'd try to find a better way than using two kinds of tags and trying to jury-rig PHP to only execute some of it. Even if it meant using a conditional on the tags to be executed later if (!$finalexecute) ... and just change that value at the top of your code or something. Sounds messy all around, but there seem to be a number of ways you could possibly do this. -TG -Original Message- From: Sven Schwyn [mailto:[EMAIL PROTECTED] Sent: Wednesday, December 01, 2004 4:16 PM To: [EMAIL PROTECTED] Subject: [PHP] Custom Open Tags 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 don't think you can do that in any efficient way with just tweaking PHP
settings, or even PHP source...
What you *COULD* do is write a PHP script to read your PHP script and
http://php.net/eval the stuff inside of ?mytag tags, and leave the rest
alone for the real PHP server to handle...
?php
//Untested code:
$file = implode('', file($php_source));
$parts = explode('?mytag', $file);
$result = $part[0];
unset($parts[0]);
while (list(, $part) = each($parts)){
$phphtml = explode('mytag?', $part);
$php = $phphtml[0];
$html = @$phphtml[1]; //File may end with mytag? so squash error
$result .= eval($php);
$result .= $html;
}
//Dump $result into some file somewhere...
?
Sounds like you inventing yet another Template language, though, to tell
you the truth, and there's already too many of them. :-)
I happen to think PHP all by itself is more than sufficient, and if
Graphic Designers can't cope with ignore the PHP tags, just hire different
Graphic Designers. :-)
You may want to look at Smarty and phplip (?) and some of the dozens of
other PHP-based template solutions. Just cuz I hate them doesn't mean you
will. :-P

Re: [PHP] Custom Open Tags
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 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

you could edit the parser rules manually, recompile PHP and it should work Sven Schwyn wrote: Hi Trevor I'm not sure, but that may allow you to use ?php ? AND % % tags at the same time.
