"); Exit ();} else {$ result = mysql tutorial _ query (" select m_uid from wk_member where m_uid = '$ xm' ") or die ('error! '. Mysql_error (); if (! Mysql_num_rows ($ result) {echo ("
Congratulations! This user can register!
");} Else {echo ("
Sorry, the user has been registered. please select another name!
") ;}} Elseif ($ ta = 0) {if (@ file_get_contents ($ xm) {echo'
