We're moving from php4 to php5, and we get this warning on one of our developers machines, but not in our php5 test setup:
Deprecated: Call-time pass-by-reference has been deprecated in C:\Workspace\Prelive\www\includes\filename etc..
The code seems to be the same in both environments, and the php.ini on the test environment has this setup for errors:
error_reporting = E_STRICT | E_ALL
We could ofcourse just fix the code so the warning will go away, but my main concern is why the test environment is not complaining about it.
There is a php.ini directive called allow_call_time_pass_reference, which may be off in the environment which does not complain about it.
