Strange pg_escape_string behavior

While using pg_escape_string to clean data being placed in a query sent to me by the user i get the following error after submitting the query with pg_execute: pg_exec(): Query failed: ERROR: invalid regular expression: invalid escape \ sequence . It seems to happen when using just a "\" or text ending with a "\" but not if a "\" is in the middle of a string of text. Why doesn't pg_escape_string catch this? To restate it maybe a little more clearly, the error occurs when i do something like: (Pretend $_POST['user_item'] has the value "car\" in it ) <?PHP $user_item = pg_escape_string($_POST['user_item']); $dbconn = pg_connect('some connection string that works'); $query = "SELECT * FROM some_table WHERE some_col = '$user_item' "; $result = pg_execute($dbconn,$query); ?> I'm running PHP Version 4.3.4, and Apache 1.3.29. -k. __________________________________ Yahoo!
