A function exists in my Visual Basic 6 DLL.
This function supports ByRef (by reference) parameters. This enables me to modify the
parameters that are coming in.
When I try to do a standard call on my function from PHP, the function works but my
variables do not come back modified like they should do.
Therefore, I tried calling the function from PHP by prefixing the parameter argument
with a "&". This worked fine, bringing back my modified parameters. However, I got
warnings from the PHP compiler to the effect of...
***************************************************
Warning: Call-time pass-by-reference has been deprecated - argument passed by value;
If you would like to pass it by reference, modify the declaration of [runtime function
name](). If you would like to enable call-time pass-by-reference, you can set
allow_call_time_pass_reference to true in your INI file. However, future versions may
not support this any longer.
***************************************************
The warning stated that my argument had been passed "By Value", even though it worked.
To summarize...
a) I cannot pass an argument By Reference to a VB DLL and make it work unless I prefix
the argument with an "&" in the PHP call.
b) The warning states that the message was passed By Value, when in fact it WAS passed
By Reference because my function changed the value of the variable.
It seems that you either need to keep the call-time "By Refence" passing in operation,
or correct the "By Reference" passing when the COM object has declared the argument of
the function to be "ByRef".
If you have any further questions, please contact me.
