我正在嘗試安裝Pligg Twitter登錄模塊Log into Pligg using Twitter OAuth。如何在不使用PEAR :: DB的情況下重新編寫此代碼？
我從上面的頁面下載了ZIP文件，並遵循了所有說明。然後我意識到其中一個文件正在使用PEAR，這不是由我的託管公司提供的。
從confirm.php整個代碼是在這裏：
如何重寫這個代碼，所以我沒有使用PEAR？這甚至有可能嗎？我真的是PHP的新手。

例8-1是建設大約詹姆斯·邦德的電影信息的HTML表格的程序。它演示瞭如何使用PEAR DB庫（隨PHP附帶）連接到數據庫，發出查詢，檢查錯誤並將查詢結果轉換爲HTML。這個庫是面向對象的，有類方法（DB :: connect（），DB :: iserror（））和對象方法（$ db-> query（），$ q-> fetchInto（））的混合。
是的。我想重寫這個東西並不難。我會弄清楚。
