Using a limit of -1 will trim all (same as without adding the limit) A limit of 0 does nothing (no trimming) A positive limit will only trim the amount of chars as specified ON BOTH SIDES. This means using a limit of 2 in trim() will strip max 2 chars from the left and max 2 chars from the right: trim(" hello ", " ", 2) returns " hello "; ltrim(" hello ", " ", 2) returns " hello "; The only problem to keep it backwards compatible is that you must add the default charlist ( \n\r\t\v\0) in order to use the limit parameter. ------------------------------------------------------------------------ [2009-07-21 17:06:58] jason at jasonsw dot com Description: ------------ It would be great if there was a way to limit the amount of characters that were trimmed from a string, in either ltrim, trim or rtrim, using a new limit parameter.
