Fix mac PHP connection MySQL error warning:mysql_connect (): No such file or directory in conn.php

Today, I used PHP to connect to MySQL database on my Mac, and there was

Mac PHP Warning:mysql_connect (): [2002] No such file ...

Details such as the following are seen:

Dirkmacbook:vote dirk$ PHPUnit mytest.php

Warning:mysql_connect (): No such file or directory in/applications/xampp/xamppfiles/htdocs/myvote/vote/conn.php on Line 25

This error, very easy to overcome this problem, enter such as the following command:

Mkdir/var/mysql

Ln-s/tmp/mysql.sock/var/mysql/mysql.sock

Cause Analysis: PHP will be/var/mysql/below to find Mysql.sock (can be found in the/etc/php.ini configuration file). But this one on our Mac doesn't/var/mysqlz this folder. and Mysql.sock file on/tmp/ Mysql.sock below. What to do?

Very easy, we just need to use ln-s to give/var/mysql/to generate a Mysql.sock file "soft connection" can be.
