PHP5＋SQLite3的组合 sqlite扩展无法加载的原因pdo.dll

　　今天搞PHP5＋SQLite3的组合，结果怎么也搞不出来，老是报
"PHP Fatal error: Call to undefined function sqlite_open() in i:\AbyssWebServer\htdocs\script\Conn.php on line 46
"
怎么也搞不出来，我基本崩溃了在php.ini里调了半天，结果PHP的错越报越大，越报越多
"PHP Warning: PHP Startup: Unable to load dynamic library './php_sqlite.dll' - 找不到指定的模块。"
"PHP Warning: PHP Startup: Unable to load dynamic library 'I:/AbyssWebServer/php/ext\php_sqlite.dll' - 找不到指定的模块。"
如此这些，突然我看到PHP报了一个错
"PHP Warning: PHP Startup: Unable to load dynamic library './php_pdo.dll' - 找不到指定的模块。"
觉得奇怪，我没配它啊并发现php/ext文件夹下许多数据库插件都有一个"php_pdo_*.dll"的版本，于是我顺藤摸瓜在网上找啊找，终于被我找到了

PDO是一个PHP的数据对象抽象层，里面写到“如果想使用PDO就要在php.ini里加入extension=php_pdo.dll”我想刚才也是报这个错，就试了一下，配置好extension_dir路径再在Windows Extensions列表的第一行加入extension=php_pdo.dll结果都好了，连php_sqlite.dll都可以用了，没想到php_sqlite.dll也会用到php_pdo.dll，可连官方文档都没有具体写要怎么配置php.ini，真是的！
　　下面我把我的配置写出来方便大家参考。
============================================
; Windows Extensions
; Note that ODBC support is built in, so no dll is needed for it.
; Note that many DLL files are located in the extensions/ (PHP 4) ext/ (PHP 5)
; extension folders as well as the separate PECL DLL download (PHP 5).
; Be sure to appropriately set the extension_dir directive.
