PHP connection MySQL database, how to set timeout

PHP connection MySQL database, how to set timeout
When you use the Mysql_connect function, the time that you exceed the setting does not return to failure.

How do I need to set this up?!

------Solution--------------------
Look at the documentation. If PHP times out, the server will react.
------Solution--------------------
Set_time_limit (25);
Add a timeout in your mysql_connect function to get an error.
You can wrap your mysql_connect function with a try catch.
Just give the idea. Good luck.
