织梦DedeCMS全局变量$GLOBALS的定义文件分析
织梦DedeCMS数据库的信息是写在data/common.inc.php文件中的,而织梦在连接数据库时使用的有一个函数是:
function Init($pconnect=FALSE) { $this->linkID = 0; $this->dbHost = $GLOBALS['cfg_dbhost']; $this->dbUser = $GLOBALS['cfg_dbuser']; $this->dbPwd = $GLOBALS['cfg_dbpwd']; $this->dbName = $GLOBALS['cfg_dbname']; $this->dbPrefix = $GLOBALS['cfg_dbprefix']; $this->result["me"] = 0; $this->Open($pconnect); } 里面的$GLOBALS是织梦的全局变量数组,凡是在函数和类以外定义的变量都在其中出现,比如$GLOBALS['cfg_dbhost']就在 common.inc.php中有$cfg_dbhost = '~dbhost~'; 而当文件加载common.inc.php文件后就有$GLOBALS['cfg_dbhost']了。
