password_compat-master Compatibility library for PHP5.5 password functionsAlthough PHP4 has developed so rapidly, it still lacks some key features compared to other popular development languages. For example, the object-oriented functions in PHP4 are not perfect and cannot capture and handle exceptions. Therefore, we are still stretched in dealing with some special issues.
In July 2004, the release of the official version of PHP5 marked the arrival of a new PHP era. At its core is the second-generation Zend engine, which introduces support for the new PECL module. The biggest feature of PHP5 is that it introduces all object-oriented mechanisms and retains downward compatibility. Programmers no longer have to write classes that lack functionality and can implement class protection in a variety of ways. In addition, there are no longer problems with object integration. Using PHP5 introduces type hints and exception handling mechanisms, which can handle and avoid errors more effectively.
While being constantly updated, PHP5 still retains the ability for old PHP4 programs to run on the PHP5 platform

without major problems. With the development of MySQL database, PHP5 is also bundled with the new MySQLi extension module, which provides some more effective methods and practical tools for handling database operations. Most of these methods are implemented in an object-oriented manner, and they also greatly improve the execution speed of database-based Web projects.
In addition, PHP5 has also improved the function of creating dynamic pictures and can support multiple picture formats (such as PNG, GIF, TTIF, JPGE, etc.). PHP5 has built-in support for the GD2 library, so it is no longer difficult to install the GD2 library (mainly in UNIX systems), which makes processing images very simple and efficient.
Most web application developers still use XML as a completely simple database. PHP5 also uses a series of simple, easy-to-use, and powerful methods to process XML documents.
Today, millions of websites, including Yahoo and Amazon, as well as numerous developers and programming enthusiasts are using PHP. From the initial PHP/FI to PHP5, PHP has developed extremely rapidly, and its future development prospects must also be eye-catching.

How to import third-party libraries in ThinkPHP

Third-party class libraries Third-party class libraries refer to other class libraries besides the ThinkPHP framework and application project class libraries. They are generally provided by third-party systems or products, such as class libraries of Smarty, Zend and other systems. For the class libraries imported earlier using automatic loading or the import method, the ThinkPHP convention is to use .class.php as the suffix. Non-such suffixes need to be controlled through the import parameters. But for the third type of library, since there is no such agreement, its suffix can only be considered to be php. In order to easily introduce class libraries from other frameworks and systems, ThinkPHP specifically provides the function of importing third-party class libraries. Third-party class libraries are uniformly placed in the ThinkPHP system directory/
