Warning:

The cPanel API 2 system is deprecated. We strongly recommend that you use UAPI instead of cPanel API 2.

Description

This function checks whether a database user exists.

Warning:

We strongly recommend that you use UAPI instead of cPanel API 2. However, no equivalent UAPI function exists.

Important:

When you disable the MySQL/MariaDB role and remote MySQL is not already configured, the system disables this function.

    'MysqlFE', 'dbuserexists',

cPanel Tag System (deprecated)

Warnings:
  • cPanel tags are deprecated. We strongly recommend that you only use the LiveAPI system to call the cPanel APIs. Examples are only present in order to help developers move from the old cPanel tag system to our LiveAPI.
  • cPanel API 2 calls that use cPanel tags vary in code syntax and in their output.
  • For more information, read our Deprecated cPanel Tag Usage documentation.
