calling a function through user input.

[Mohawk Mawk]

Hey guys.
So heres yet another question to a problem where I would have no idea
where to look for the answer for so I turn to you :)

Say my sites administrator wants to write a news update or blog or
whatever. Something like this

"Added a new gallery from my trip to Phuket, enjoy:
[GID=24]
If you liked it tell me."

I want the [GID=24] to get replaced by my galery loading function
(very nifty and handy) so it would turn into something like this

echo "Added a new gallery from my trip to Phuket, enjoy:
".galery($GID). "
If you liked it tell me.";


I chose this [GID=24] because it is similar to burning board code. I
would also like to include a command like [PID=45] witch would run my
picture function.

any ideas what functions I am looking for?

preg_replace_ca llback()

http://fi2.php.net/manual/en/function.preg-replace-callback.php

example:
preg_replace_ca llback('/\[GID=([\d]+)\]/', 'galery', $input);

But galery will recieve an array of matches, not just an id, so you'll maybe
need to modify it a bit. Also I haven't tested this at all, the example is
just to illustrate the idea...

thank you very much, I inserted a handling function:


function garray($input){
return gallery($input[1]); /* $input[0] is '[GID=X]' and $input[1]
is 'X' */
}

$news="See my galleries one [GID=1] and two [GID=2]";
echo preg_replace_ca llback('/\[GID=([\d]+)\]/', 'garray', $news);

it works like a charm, this is the beginning of a whole bunch of new
possibilities for the administrator to write news.
thank you very much
