[users@httpd] SSI functions to compare dates?
Hi,
I'm trying to use SSI (via XBitHack) to include a file or a bit of
text in certain existing web pages only until a date I set in code.
In other words, I want my pages to display certain text until an
expiration date, and only until then. I know how to do this in PHP,
but I don't want to have to rename my files from .html.
This is how I've approached the problem:
<!--#set var="now_date" value="$DATE_LOCAL"-->
<!--#set var="exp_date" value="[something goes here that is
based on the date I want the include-file to stop appearing]"-->
<!--#if expr='"now_date > exp_date"' -->
<!--#include virtual="../../includes/file_to_include.inc" -->
<!--#endif -->
Here are my questions:
1. In the third line above, would now_date (derived from DATE_LOCAL)
be in Unix time? Or else in what form?
2. Is there a function I can call in the second line above to encode
a date into Unix time (or whatever the answer is to my first
question?)
Or, is there a better way to approach this problem?
I'm running Linux Red Hat 9 and Apache 2.0.42.
Thanks!
Doug Lipman

Thanks so much! I'll try PHP by the file.

You can also put a <Files> section inside an .htaccess file that
activates php only for a single file. If you do that, you probably
wouldn't see any significant speed decrease. And in any case, I'd
guess that the difference between ssi and simple php probably isn't
huge anyway.

I take it that you mean I can configure PHP to parse all .html files
in a web directory, by using an .htaccess file. If I do that, will I
run the risk of a major slow-down of my site?

First, it is not necessary to rename your files to use PHP. PHP can
be configured to work on any extension, not just .php.

See
http://httpd.apache.org/docs/2.0/mod/mod_include.html
where you will find the "timefmt" option of the "config" element.

Not as part of SSI. You can generate that using standard time
functions under c/perl/python/whatever.

mod_rewrite can do rewriting conditional on date, which is an
alternative approach.
If you are most comfortable with php, I'd simply use that.
