PHP Code Style Issue - function Foo( array & $moo )

It used to be that I could set up the PHP code style so it would insert a space between the & and $ in the following line:

function Foo( array & $moo )

But that option has since disappeared in the newer version of PhpStorm - I cannot find it anywhere.  Now, when I format my code it becomes this:

function Foo( array &$moo )

There is no longer any space between the & and $.  For the life of me, I cannot figure out how to get this code style option working again.  This is really annoying because I have thousands of files in Git and now when I code format a file, it Git will show differences on those lines, and I have to manually "fix" those lines after code formatting the file.  Please help.
