ThinkPHP version: 5.1.*

使用 ThinkPHP 框架连接PGSQL时遇到的坑, 记录下来...避免一次一顿百度....

改配置

修改 /config/database.php 这个配置文件

connect pgsql config

• 如果此时对数据操作会报错

  

  could not find driver

开扩展

修改 php.ini 打开连接pgsql需要的扩展, 如果没有请到 http://pecl.php.net/ 下载对应版本的扩展
修改了 php.ini 别忘了重启apache/nginx

php extensions

执行sql

在使用之前请先在 navicat 中运行一下SQL, ThinkPHP中自带这一个SQL文件
/thinkphp/library/think/db/connector/pgsql.sql
