What does php underlying development mean?

With the rapid development of the Internet, PHP has become a widely used language. As a server-side scripting language, its application range is very wide, from simple dynamic websites to huge enterprise systems, all can be implemented using PHP. In the field of underlying development of PHP, you need to have an in-depth understanding of the PHP language itself and carry out efficient development through underlying development skills.

So, what is PHP underlying development? PHP underlying development does not refer to the library files used in the PHP development process, but refers to the process of modifying and optimizing the PHP source code. For example, optimize the PHP runtime environment, modify the PHP compiler to improve compilation efficiency, write new functions and classes, etc. That is, through development at all levels, we can deeply understand the internal mechanism of the PHP language and carry out efficient development on this basis.

First of all, PHP underlying development requires mastering basic knowledge. Basic knowledge includes compilation principles, computer architecture, operating system principles, etc. Only on the basis of these basic knowledge can we have an in-depth understanding of the underlying mechanism of PHP. These underlying mechanisms include Zend Engine, memory management, interpreter, etc.

Secondly, PHP underlying development requires mastering certain data structures and algorithms. A data structure refers to a data format designed to hold data, and an algorithm refers to a series of steps to accomplish a specific task. In the underlying development of PHP, you need to master some efficient data structures and algorithms to implement various functions, such as hash tables, trees, sorting algorithms, etc. These are important tools for achieving high performance.

Next, PHP underlying development requires mastering some common development tools and technologies. For example, debuggers, performance analysis tools, code review tools, etc. These tools and technologies can effectively improve development efficiency and quality, allowing developers to better control the behavior and performance of code.

Finally, PHP underlying development requires continuous learning and exploration. The underlying development of PHP is an area full of challenges and opportunities. It requires continuous learning of new knowledge, mastering new skills, and constantly thinking about how to improve the performance and maintainability of the code.

In short, PHP bottom-level development is a highly professional technology. It requires an in-depth understanding of the internal mechanism of the PHP language, mastery of certain basic knowledge, data structures and algorithms, commonly used development tools and technologies, and Keep learning and exploring. Only in this way can we go further and further on the road of PHP development and create high-performance, high-quality applications.
