[php]
define('DEDEADMIN', preg_replace("/[\/]{1,}/", '/', dirname(__FILE__) ) );
Note that the first in [\/] is actually an independent text character, and / means escaping the meaning of / into an ordinary text character
If you replace the content in the regular expression [] with [/] or [/\], it will not work. An error will be reported.
