Php and tomcat are successfully configured, but the database connection fails, and phpinfo () can correctly display the configuration information.

Can mysql be connected successfully in the command line.

Phpinfo () correctly displays the configuration information.
What does it mean?

Mysql is not installed on my machine, but phpinfo can also display "correct information "...... It's just the dll information of php itself. first confirm that your mysql is okay and then study the php

PHP Startup occurs, most of which is an extension failure.
Since you encounter an error when using mysql, it means that the loading of php_mysql fails (he also needs a support database)
You need to place the php installation directory in the search path of the operating system.
