Hello,
Can you please tell me if there's already a set of PHP functions for
translating SSI commands to PHP?
I'm looking to do two things -- one difficult, one easy -- using PHP
on a hosted server.
My client has web pages that use Server Side Includes, and one
sub-site that uses PHP. The task is to make the PHP sub-site use the
same SSI includes as the rest of the site to maintain a consistent
code structure. I can simply use include_once() to include each SSI
include; that works fine. However, I'd like to recognize and replace
one of the SSI instructions with a more nuanced PHP instruction that
will insert dynamic information from the sub-site's environment.
1. include SSI files A
2. include SSI file B, Recognize B and replace it with some PHP code
3. include SSI file C
and i can't actually do that b/c PHP gets run first and then SSI
instructions.
So the difficult thing I want to do is to read the SSI files
(literally, using fread or similar), translate them to PHP ('include
virtual' -- include(), set var=foo value=bar -- var foo = bar,
etc), and then execute them.
Then the simple thing I want to do will be recognizing the commands I
want to replace or modify and doing so.
Since this is a hosted solution, I don't believe I can install any PHP
modules, and I'll have to use some functions instead. Does that
already exist, please?

I think you didn't provide enough details to get a more accurate suggestion
of a solution, but here goes... Is 'include SSI file B' always included and
always need to be replaced? If so, that's a very apparent solution. If
not, what are criterias? URL? Query parameter(s) and/or value(s)? Certain
user(s)? Certain group(s) of users? Certain hour of the day? Certain user
agent(s)? etc... Regardless of how dynamic any site is, there's a always
some kind of pattern. What you need to do is identify that pattern and do
what you need accordingly. What about having PHP read those files to be
included and output without having to rely on SSI mechanisms?
I'm just curious... since PHP is OOP and, IIRC of SSI, the use of SSI limits
the full potential of OOP and PHP. Is the control of the application and
configurations beyond yours?
Regards,
Tommy

I used SSI circa 1990's (before PHP) to include common code. However, it required me to also have .shtml suffixes on the files that used them. Since PHP, it's simple to use PHP include statements to accomplish the same thing. So, I see no reason to use SSI's at all. What am I not understanding in this problem?

Re: [PHP] Server Side Include translator as PHP functions
Tedd, The crucial detail you're lookign for is my lack of choice or control in the matter, for all sorts of reasons that are actually quite stupid but not possible for *me* to change, and not possible for anyone else to change quickly. Thus I am looking for a solution to the problem at hand, instead of a suggestion for what the entire org should be doing instead. I know what they should be doing instead, but that's not my decision. It's not like I'm building a new website this way; I'm trying to move forwards with an existing and large website. The more different code-bases we have for different parts of the site, the harder it will be to actually change to something else (PHP-based, I pray). -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[1] http://httpd.apache.org/docs/current/howto/ssi.html
Tommy,
Yes, thanks, I did see that:
change !--#include virtual=/includes/old/file/B.inc --
to !--#include virtual=/path/to/php/code2exec.php --
!--#include virtual=/path/to/php/code2exec.php --
does not work on our servers. (I hesitate to say that it doesn't work
anywhere; I don't have enough experience with that.)
What happened when I tried this is that the page displays the raw PHP
instead of the results of the PHP. The server executes the PHP first,
and then executes the SSI instructions, such that the following *does*
work.
?php include('/path/to/php/code2exec.php'); ?
(mind you, I've seen plenty of notes that you should/have to use
virtual() instead)
Regarding SSI not doing anything dynamic: Yes, that's mostly true. The
only dynamism you can get is using if/elsif/else statements while
checkign things like the current URL path, which are ridiculously
clunky.
So the point of this question was to find an *existing and tested*
non-module set of functions that I could employ to translate a
particular include into a set of PHP commands, and then use PHP to add
some dynamic content.
And do you see my main point here, please? I'd use PHP to add some
dynamic content WITHOUT CHANGING THE MAIN CODEBASE that is
unfortunately but definitely stuck in SSI.
I'll probably have to skip that idea, but I'll try to look elsewhere
for such a set of functions. I'd like to write them in the future, but
that's not going to happen within the next couple days. And if anyone
is still scraping their brow at the absolute HORROR that we are using
SSI instead of the PHP that we should be using, please note that the
whole point of keeping the codebase the same everywhere is to move
everything into a new, modern codebase *real soon*.

If not, then I think I would pass on working the site. In my experience, it's not worth my additional time to try to work around out of date technologies. It is also been my experience that when I am confronted with something large scale, and when approved by the client, I simply do a site-wide find and replace (namely change !--#include to ?php include) and then evaluate all occurrences prior to changing. That usually gives me a good idea of the breath of the problem. In addition, considering the !--#include has basically the same purpose as ?php include, while it may be a wide-spread problem, I do not see it as a serious problem to address. Certainly, when including files that have a different suffix .shtml as compared to .php you will find that the Server will treat them differently but that's pretty easy to fix -- just change the files suffix or possibility write code in a .httacess file that would cause the interpreter to consider shtml files the same a php. Of course, I may not fully understand the problem.

The more different code-bases we have for different parts of the site, the harder it will be to actually change to something else (PHP-based, I pray). At the time when I was working with ASP and SSI, I suggested my client to better rewrite the application in OOP language then do patchworks. But he _insisted_ on keeping existing code base. So I did patchworks here and there. It got to the point where he finally wanted some additional features much later that it was impossible to do with ASP and SSI. It was then that he finally decided to go with my suggestions, which is months later. During that time, I could have easily rewritten the application in PHP. That's why I suggested you to consider the site's function and features. It maybe just one thing that the client/boss wants now, then another, and another... etc... Eventually, you're going to through the same thing I did. Good luck, Tommy
[PHP] Re: PHP Download Of Application Question?
I am looking for a way to download a C based application binary, from an Apache / PHP server, via a client side Web Browser, and execute it seamlessly on the client side PC without storing it permanently on the client side hard disk drive. Temporary storage would be ok. I know this can be done because I have observed it operation in various applications. This concept allows a authorized customer to have the use of an application via the web without being able to keep or share the application binary. I am open to other approaches beyond Apache and PHP. So any ideas out there? Thanks for the help Thomas Dineen That sounds like the kind of thing Java Web Start does. There's lots on Google about it. http://download.oracle.com/javase/6/docs/technotes/guides/javaws/ -Alex
