} Actually I did mean to use the $patterns[] and $replacements[], php
} will automatically increase the index for you kinda makes adding
} different pattern/replacement arrays easier in any order.
}
} The array will by default be FIFO.
Ok, gotcha.

} What does this return?
}
} I'm a bit confused right now..
The query simply returns one row with all the htmlstuff [width, height,
caption, image_holder, etc] for one image. In otherwords, $message might
contain:
---------------------
Hello world, look at my [b]cat[/b]: ###Image1### Nice, huh?
And now look at my [b]dog[/b]: ###Image2### Not so nice, eh?
---------------------
I'm using a big preg_replace call to replace any of that custom formatting
tag [eg: [b][/b]] as well as the ###ImageX### tags. Instead of replacing
###Image1### with some formatting code, I need to look up ###Image1### in
the database, which stores the formatting codes. So the in the above
query, $thephoto[0] contains '###Image1###', since it is the first photo
on the page. However, when preg_replace finds a 2nd photo, with a
image_holder of ###Image2###, the select statement is still run against
the first image place holder, ###Image1###. So I need to advance the
counter before running the SQL statement
If I leave out the sql stuff and do something like this:
$patterns[3] = "/###Image(\d+)###/si";
$replacements[3] = "My Photograph\$1";
Then the page sucessfully substitutes "My Photograph1" for every place
that $message contained ###Image1### and "My Photograph2" for every place
that $message contained ###Image2###.
So I need to somehow run preg_match on that part of $message in order to
extract ###Image1###, ###Image2###, ###Image3###, etc from the message and
look them up in the database. I think. :-\
} after the user enters in his stuff, he wants, in your CMS and before you
} save it, parse it for all the special tags you have and keep track of it
} somewhere. That way when you output it (in this script) you only need
} to apply the necessary pattern/replacements before outputing it to the
} browser.
Good idea! Thanks very much!
Thanks again for your help, and time, with this. I do appreciate it.
