You can do regular expression matching in MySQL and I think a few other
servers too, but that's not the same as regular expression replacement
like you can do with PHP.. It just returns a boolean true/false
depending on whether or not the match works.

i'm a bit confused. if i'm getting you right heres my 2 cents:
first you do sql query using DISTINCT
when the result are returned to you, you can then run thru the result
array
using preg_replace. heres an example:
$aVar = array(
'animal-dog-5',
'animal-dog-3',
'animal-cat-1',
'animal-cat-22',
'animal-bird-5',
);
$aResult = array();
foreach ($aVar as $value) {
$tmp = preg_replace('/-\d*$/', '', $value);
$aResult[$tmp] = $tmp;
// if you want to conserve a bit of resources asign NULL;
// $aResult[$tmp] = NULL;
}
var_dump($aResult);
hth,
john
p.s.
i'm not sure if it is possible to use regular expression in a sql
query. can
anyone comment on this? thanks.

Well, its not really a search.... that would be way easier. :-) What
I'm looking for is a query that will give me the complete list of
items that are distinct, minus the last number after the last hyphen.
animal-dog
animal-cat
animal-bird
