- Efficiency: PHP 4.0 uses resource allocation mechanisms and object-oriented programming, in addition to session management features. It eliminates the unnecessary memory allocation.
- Security: Many encryption functions are supported by PHP to secure the data.
- Object-Oriented: The object-oriented programming features are added in PHP 4.0.
Advantages of PHP:
- It is supported by all Operating Systems like Windows, Linux, Unix, etc.
- It is easy to connect with the database to store and retrieve data from the database. Multiple databases can also be integrated with PHP.
- It is the fastest programming language compared to other programming languages.
- PHP frameworks and tools are used to protect web applications from outer attacks and security threats.
Disadvantages of PHP:
- Since PHP is open-source so its code is visible to all programmers. If any bugs exist in the source-code then its weakness can be explored by other programmers.
- It is not suitable for large applications becuause its maintenance is difficult.
- The error handling of a PHP framework is not good.
