学习php编程遇到
Uncaught exception ‘PDOException‘ with message ‘could not find driver‘
或者
Undefined class constant ‘MYSQL_ATTR_INIT_COMMAND‘
整两个问题,网上找了很多资料,很多是这样解决的
配置php.ini文件添加extension=php_pdo_mysql.dll，这样就开启pdomysql扩展库
但是我没有解决问题,问题还是老样子,后来在stackoverflow 找到了问题所在
具体链接http://stackoverflow.com/questions/7086859/pdo-drivers-no-value-in-windows
问题出在了
extension_dir = "ext"
改成绝对路径就可以了
; Directory in which the loadable extensions (modules) reside. ; http://php.net/extension-dir ; extension_dir = "./" ; On windows: extension_dir = "D:/php-5.4.11-Win32-VC9-x86/ext"
原因
in php.ini and php -m was starting fine and reporting that it loaded pdo_mysql, but when I ran phpinfo.php through apache, the driver was missing.
I fixed it by changing the extension_dir to an absolute path. I‘m guessing it got confused when running through Apache and made it relative to something else.
我固定它通过改变extension_dir绝对路径。我猜它混淆了运行时通过Apache和相对于别的东西。转载：http://blog.csdn.net/bao0682/article/details/46827111
