[Bug 1642745] [NEW] Error: Only variables should be passed by reference

 

Public bug reported:

When I go to page webservice/testclient.php

I see the error debug message:

"Only variables should be passed by reference"

This is coming from a call to array_shift() that has a call to
array_keys() as a parameter.

We should assign the result from array_keys() to a variable and then
call array_shift() with this variable as a parameter.
