I've got a PHP script that needs to invoke a shell script but doesn't care at all about the output. The shell script makes a number of SOAP calls and is slow to complete, so I don't want to slow down the PHP request while it waits for a reply. In fact, the PHP request should be able to exit without terminating the shell process.
I've looked into the various
If it "doesn't care about the output", couldn't the exec to the script be called with the
& to background the process?
EDIT - incorporating what @AdamTheHut commented to this post, you can add this to a call to
" > /dev/null 2>/dev/null &"
That will redirect both
/dev/null and run in the background.
There are other ways to do the same thing, but this is the simplest to read.
An alternative to the above double-redirect:
" &> /dev/null &"
