  Problem 1
    - The requested PHP extension ext-pdo_sqlite * is missing from your system.
Install or enable PHP's pdo_sqlite extension.

今天在github上下载了一个Symfony的demo,解决报错,各种查找,最终还是找到了php.ini这个文件(文件在你的 php安装目录下面：我的C:\php5\php-5.5.30-nts-Win32-VC11-x64，)

打开文件找到以下代码:(解决办法就是我写的去掉分号！！！！！！！！！！)

.....

;extension=php_oci8_11g.dll  ; Use with Oracle 11gR2 Instant Client
extension=php_openssl.dll
;extension=php_pdo_firebird.dll
extension=php_pdo_mysql.dll
;extension=php_pdo_oci.dll
;extension=php_pdo_odbc.dll
extension=ext\php_pdo_pgsql.dll  (2:我顺便把这里的";"分号去掉了)
extension=php_pdo_sqlite.dll     (1:我把这里的";"分号去掉了)
;extension=php_pgsql.dll
;extension=php_pspell.dll
;extension=php_shmop.dll

......

然后保存就ok了，你可以找到etx目录下，那里面全是关于数据库的脚本；

我现在觉得使用哪个，就把哪个前面的分号去掉，但不知道是不是这样子，至少没有抱错！
