将SVN与PHP一起使用 - 在现有目录上添加命令失败

Question

So basically I want to be able to do this:

        /*
            Runs command and checks return code of last command run. Throws SVN exception if non-zero status code is returned. The output of the command otherwise.
        */
        public static function runCommand($cmd)
        {
            //Redirect error to stdout
            $cmd .= " 2>&1";

            $output = array();
            exec($cmd, $output, $status);
            $output = implode("
", $output);

            if($status != 0)
            {
                            //custom exception class - nonimportant
                throw new SvnException($output);
            }

            return $output;
        }

The issue is that svn add considers it an error when you try to add a directory that is already under version control so it returns an error status code. Is there anyway to fix this issue without putting in a hack to look for svn add commands and ignore the error if is the "directory already exists one"?

Specifically, is there some SVN commands I can use to tell if the folder is under version controlt, or arguments that I can use so that svn add does not return an error if the directory is already under version control.

You can ask svn if the directory exists. If you want your add function to mimic the svn one, just throw your Exception and have the caller deal with it. If you want it be silent when the directory already existsm add the check here.
