Local function variables not visible when opcache is enabled

Hi,

When opcache is enabled, debugger doesn't show local variables in functions. When opcache is disabled, all variables are shown correctly. Is it possible to configure php to enable opcache and view all local variables in functions?

regards,
Marcin

opcache is not compatible with php debuggers. It's recommended to turn it off if you want to debug.

When I debug php 5.6 on another remote machine (with opcache enabled) with the same local PhpEd instance everything works ok. I can't figure if there are any settings of opcache to make it work with php 5.6 and not work in php 7.4.
Any hints, please?

OpCache is an evolving project. Its features are evolving too and compatibility changes over time. What was not broken in 5.6 is broken now. What was crashing in 5.6 is not crashing now. As of php7.3 and higher, DBG is not the only php debugger that affected by OpCache.I'm not aware of any other php debuggers that would work with OpCache under php 7.3 or higher.
Sorry, we don't have any influence on OpCache future plans and fixes. You can try to find a way to report your findings and suggestions to OpCache developers directly.
