This and the previous chapter introduced you to the entire gamut of PHP’s OOP features, both old and new. Although the PHP development team was careful to ensure that users aren’t constrained to use these features, the improvements and additions made regarding PHP’s ability to operate in conjunction with this important development paradigm represent a quantum leap forward for the language. If you’re an old hand at object-oriented programming, hopefully these last two chapters have left you smiling ear-to-ear over the long-awaited capabilities introduced within these pages. If you’re new to OOP, the material should help you to better understand many of the key OOP concepts and inspire you to perform additional experimentation and research.
The next chapter introduces yet another new, and certainly long-awaited, feature of PHP 5: exception handling.
