When observing a function via observer API or zend_execute_*, these additional functions allow looking up the function's type and the filename (for user functions and eval'd code). From ExecuteData we can also retrieve the return value in a number of ways.

[nitpick] Consider returning a more type-safe enum instead of a raw u8. This would make the API more self-documenting and prevent invalid function type values.
Suggested change
| unsafe { self.inner.type_ } | |
| pub fn get_type(&self) -> Option<FunctionType> { | |
| FunctionType::from_u8(unsafe { self.inner.type_ }) |

This pull request adds new utility methods to the
ZFuncandExecuteDatastructs in thephpercrate, providing improved access to function metadata and execution context information. These additions make it easier to retrieve function types, filenames, line numbers, and return values when working with PHP internals from Rust.Function metadata access improvements:
get_typetoZFuncfor retrieving the function type (e.g.,ZEND_USER_FUNCTION,ZEND_INTERNAL_FUNCTION).get_filenametoZFuncto obtain the filename for user-defined or eval'd functions using theop_array.Execution context access improvements:
get_linenotoExecuteDatato retrieve the current source code line number for user or eval'd functions.get_return_value,get_return_value_mut,get_return_value_mut_ptr, andget_return_value_ptrtoExecuteDatafor accessing the return value in various forms (immutable, mutable, and raw pointers).
