This question already has an answer here:
I am using Zend framework 2 in my application. Recently, my website got down. The server contact person told us MySQL reported most of the connections were timing out. The reason he gives us is that the MySQL connections are not calling mysql_close() function before exiting.
Do we need to use mysql_close() in applications?

分享 Based on the comments of your question, using mysql_close is unnecessary since you are using PDO.
As @Tim Fountain mentioned in the comment, PHP will automatically close the connection once the script is done running, unless if you are using the persistent connection (which is usually causes problems, I learned this in a hard way).
If the connection to database server keeps timing out, there is a problem on the connection between PHP and MySQL database server, not the script.
