Without invoking the ssh tunnel within a seperate process, that means you will have to create a new tunnel for each invocation of the script – and you can’t share an tunnel created by another instance since you don’t know when it will terminate. So in addition to the connection overhead you need to manage a pool of local sockets.
The short answer is that it’s just not feasible.
A longer answer is that you can start daemons/long running processes from within PHP but there are a few caveats. So if you can use the program execution functions and have access to a set of POSIX tools using the command line tools then it is possible. It’ll be a lot simpler to implement this if you can set up a key pair (with an necryted private key) to avoid having to parse the I/O to the program to inject the password at the right point (or use something like ‘expect‘ to handle it).
