Req #49007 [Com]: Add limit option to trim functions

Edit report at http://bugs.php.net/bug.php?id=49007&edit=1 ID: 49007 Comment by: jthijssen at noxlogic dot nl Reported by: jason at jasonsw dot com Summary: Add limit option to trim functions Status: Open Type: Feature/Change Request Package: Strings related Operating System: * PHP Version: * Block user comment: N Private report: N New Comment: I've added a patch (both 5.3 and trunk) for adding a "limit" to the [lr]?trim() functions. 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.
