OK, here's possibly a weird one. Is there any way to do string comparisons
and ignore all non-alphanumeric characters? For instance, check "foobar" and
have it match an existing record of "f$#!oo B(a)*R".

check for "mysql regex" on search engines.

I looked into that, but it only seems useful to specific pattern matching -
I can't find any way to selectively NOT match something that is unknown,
while continuing to match something else (and not have it also match normal
characters, such as "footbar"). After some Googling I found someone who
merely wanted to ignore spaces, but alas it looks like even that cannot be
done with mere database commands.
So I many have to go the inefficient route: retrieve the entire column and
do my own processing.

So I may have to go the inefficient route: retrieve the entire column and
do my own processing.
If you do this search often, make an extra column and store the "cleaned"
version of the column.

I have a download.php that handles some form posts from a html page. It
attempts to use Header(Location: ......) to download a file. It works when
out of ssl, but when under ssl, I get the 'Headers already sent' error. The
ob_start() and ob_end_flush() calls are being ignored. I theorize that the
Host's SSL package has to allow buffering, or maybe it is the Server?
any suggestions or resolutions will certainly be appreciated on this.

I'm using the following in a page that I'm testing in Mozilla:
p.actionLinkBlock {border: 1px #000000 dashed; padding: 0.2cm; width: auto}
But the dashed border is extending to the right-edge of the screen. I
want it to only extend as far as it needs to to nicely contain the
content within (a couple of links).
Is width: auto the wrong property to do this? Is Mozilla rendering the
style wrong?

What are the mechanisms to make words like a/an/the in text and varchar
character fields ignored when performing SELECT and utilizing ORDER BY
in SQL queries?
I've done some hunting around into documentation on character sets (but
they are geared mainly at character-by-character rules) and saw some
reference to string collating and stop words -- but not seen any of this
all put together.
Thanks for any assistance,

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
