First install php5.5.14 (mysql problems)

The first installation of php5.5.14 (mysql problems) because I use apsaradb, mysql is not required for all servers. after php5.5.14 and apache are installed. The program used is wordpress. Always said: Your PHP does not seem to have installed the MySQL extension necessary to run WordPress. Is it necessary to install the mysql client. Or why? I hope you can help me. My first contact with php

Instead of the mysql client, you need to install the mysql extension of php.

Sudo apt-get install php5-mysql

Php 5.5 no longer supports php_mysql extension. use php_mysqli extension instead.

How to configure it .. My phpInfo address is www.4acms.com/test.php.

Solved ..
Compilation parameters:
-- With-mysql = mysqlnd
-- With-mysqli = mysqlnd
-- With-pdo-mysql = mysqlnd
Mysqlnd is added in php5.3 and later versions, and mysql must be compiled in versions earlier than 5.3.
