Runtime Configuration

The behaviour of these functions is affected by settings in php.ini.

Here's a short explanation of the configuration directives.

uopz.disable bool

If enabled, uopz should stop having any effect on the engine.

uopz.exit bool

Whether to allow the execution of exit opcodes or not. This setting can be overridden during runtime by calling uopz_allow_exit().

uopz.overloads bool

Enables the ability to use uopz_overload().

Note: When running with OPcache enabled, it may be necessary to disable all OPcache optimizations (opcache.optimization_level=0).
