check for existing, persistent SQLite connection in PHP

PHP supports the use of persistent SQLite connection. However, problem arises in trying to run maintenance scripts (like file backup), with such a connection opened. These scripts are likely to be run without a server restart every now and then, on periods of low traffic.

The question is : How to check if there is currently an SQLite persistent connection, without opening / calling one (hence creating the connection).

Answer

If you have access to shell_exec() or exec you can run a shell command to check to see if a sqlite process is running using something like top or maybe a command like lsof -i -n -P | grep sqlite assuming sqlite is the name of the process.
