thinkphp study notes 2

First of all, 3.2.3 database classes and drivers have been rewritten using PDO (Make sure your server environment has PDO extension enabled), so no matter what database it is, it is implemented based on PDO, so DB_TYPE no longer supports PDO Settings must use the actual database type settings, and there is no longer a distinction between mysql and mysqli (just set it to mysql uniformly) The role of the DB_DSN parameter has changed, so it no longer needs to be set by default, just set it to an empty string.

That is to say

The original pdo configuration is

'DB_TYPE'=>'pdo',
'DB_USER'=& gt;'root',
'DB_PWD'=>'111',
'DB_PREFIX'=>'think_',
'DB_DSN'=>'mysql:host=localhost;dbname=thinkphp;charset=UTF8' ,

3.2.3 version of mysql should be changed to the following

'DB_TYPE'=>'mysql',
'DB_USER '=>'root',
'DB_PWD'=>'111',
'DB_PREFIX'=>'think_',
'DB_DSN'=>'mysql:host=localhost;dbname=thinkphp;charset=UTF8',

The above introduces thinkphp study notes 2, including various aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
