php类中常量的定义

先看下面一段代码:

     class SVN {
               const DEFAULT_PATH = "/tmp";
               const SVNLOOK_CMD = "/usr/bin/svnlook";
               const REVISION_DIR = dirname(__FILE__).'/revisions';
               const REVISION_DIR_ZIP = dirname(__FILE__).'/zips';

提示

PHP Parse error:  syntax error, unexpected '(', expecting ',' or ';' in /app/code/script/svn_hooks/handle.php on line 6

原来表达式不能出现在常量里;
