own php function

Hello,

I would like to create an own php function which just prints a certain
report as phpinfo() does.

The function shall not be included into the general php code, I just
want to patch my own installation. Where would be a good place for the
function? I don't want to create an extention which would have to be
included into the configure script, I guess thats too much work. The
function shall be able to access the Host-header of the webserver.

Regards
Marten

You could make your own extension.. in order to write them (Because
after writting one you realize you need more) you should be using
either that book by Sara:
http://www.amazon.com/dp/067232704X?tag=libssh2projec-20&camp=14573&creative=327641&linkCode=as1&creativeASIN=067232704X&adid=01HQSM6RF0V2X97Y0VPW&

Or

Start by reading:

http://devzone.zend.com/article/1021-Extension-Writing-Part-I-Introduction-to-PHP-and-Zend

And I would probably direct you towards pecl-dev@lists.php.net

The reason I am mentioning to make your own extension is to save you
the hassle of migrating from a version to another. If you make your
extension you can easily package it, and when you recompile/re-install
php, you just pecl install MyOwnExtension or such.

A custom extension looks like the perfect place for such a thing since changes
in PHP will less likely break it and you can simply copy it from PHP version
to PHP version without having to care aobut changes in PHP...

I'd also recommend that you wrap your function into an
extension of its own, it is not as hard as it seems ...

(warning, shameless plug to follow as usual)

... especially if you let pecl-gen take care of all the
infrastructure work so that you can focus on the desired
functionality.

Assuming that your function does not take any parameter
and does not return anything your pecl-gen input file
would look like this:

<?xml version="1.0"?>
<extension name="myinfo">
<function name="myinfo">
<proto>void myinfo(void)</proto>
<code>
<![CDATA[
php_printf("your output here\n");
]]>
</code>
</function>
</extension>

Once you've installed CodeGen_PECL from PEAR
you can create a working extension from this
using the following sequence of commands:

pecl-gen myinfo.xml
cd myinfo
phpize
configure
make
sudo make install

After that you can load the extension in
php.ini using

extension=myinfo.so

For more details on pecl-gen see:
