UOPZ

User Operations for Zend

The uopz extension is focused on providing utilities to aid with unit testing PHP code.

It supports the following activities:

• Intercepting function execution
• Intercepting object creation
• Hooking into function execution
• Manipulation of function statics
• Manipulation of function flags
• Redefinition of constants
• Deletion of constants
• Runtime creation of functions and methods

Note: All of the above activities are compatible with opcache

PHP 7

PHP 7 is a different animal to PHP 5, making uopz work for PHP 7 was difficult, and required huge internal changes to uopz.

This has brought about a new API that should allow nearly all the same dark magic as in PHP 5.

Sorry for breaking BC ...

Installation

• uopz should be loaded before opcache.

Testing

Running the test suite

After make has executed, run:

``make test``
