$DB = new t3lib_DB();
$DB->connectDB();

问题：

在一个typo3自定义脚本中，我在上面看到了define()，但实际上在整个脚本中，并没有使用那些常量，例如TYPO3_MOD，TYPO3_db_host......为什么将它们define()放在脚本中？或者是typo3系统的要求，如果是这样，通常我们define()应该在脚本中放入什么？

该类t3lib_DB使用常量来连接到用于typo3 的数据库。

/**
 * Connects to database for TYPO3 sites:
 *
 * @param string $host
 * @param string $user
 * @param string $password
 * @param string $db
 * @return  void
 */
function connectDB($host = TYPO3_db_host, $user = TYPO3_db_username, $password = TYPO3_db_password, $db = TYPO3_db) {
        // If no db is given we throw immediately. This is a sign for a fresh (not configured)
        // TYPO3 installation and is used in FE to redirect to 1-2-3 install tool
        ...

但这不是获得与数据库的连接的要求。您也可以直接将值传递给$DB->connectDB();
