A PHP-driven script to determine if the environment is configured

Dear list,
e-Greetings,

I've developed some PHP-driven web applications. These applications will be
installed on different
linux-based servers (typically Debian and Redhat). Usually, after I copy the
files to the
server, they DO NOT WORK, so I spend hours to debug the problem. Problems
are very funny,
for example, the program is giving strange errors, and it is not working
because "short_open_tags" are off !

I decided to write a PHP script to check if server's configuration meets my
requirements.
- checking whether some php extensions are loaded, eg. MCrypt.
- checking wheather short_open_tags is ON
- checking whether mod_rewrite is enabled
- etc.

Here's my question:

- How do you check if .htaccess is working, *** via php code *** ?
It's easy to check if .htaccess exists (@php: file_exists), but how to make
sure if .htaccess is working?!
- How do you check if AllowOverride is set to All in apache's configuration?

Please let me know what do you think. Thank you in advance.

Make sure that you did your scripts executable(chmod +x)
You can check .htaccess that way:
create .htaccess if folder with script, override some directive thru
it, like php's max execution time.
then create php script, get php value that you've
changed(max_execution_time), compare to the value you gave in
..htaccess, if values are the same, .htaccess is working!

I'd advise against using short PHP tags, as they cause all sorts of
problems with outputting XML-based code, and as you've seen, it's
doesn't make your code very portable. For the sake of a few keystrokes,
is it really worth it? Also, I believe they are being phased out as of
PHP6, so it might be time to think about updating your code a bit!
