3. JIT. When enabled it can start debugging Just in Time when an error happens.

It supports back-trace, e.g. displays a list of all procedures with their local variables, the current execution position reached from. In other words you can watch local variables or functional parameters in all active and nested scopes.

• It has embedded profiler, so now it's easy to find out a bottleneck in the scripts.
• It allows multiple debugger processes running simultaneously.

PHP_Dyn
