Object-oriented programming (OOP) is a basic skill for our programming, and PHP5 provides good support for OOP. How to use OOP ideas to perform advanced programming of PHP is very meaningful for improving PHP programming capabilities and planning a good Web development architecture. Below we will use examples to illustrate the practical significance and application methods of using PHP's OOP for programming.

When we usually build a website with a database backend, we usually consider that the program needs to be suitable for different application environments. What is different from other programming languages ??is that in PHP, the database is operated by a series of specific functions (if you do not use the ODBC interface). Although this is very efficient, the encapsulation is not enough. If there is a unified database interface, then we can apply it to multiple databases without making any modifications to the program, thus greatly improving the portability and cross-platform capabilities of the program.
