Getting Started with PHP: PHP and C

PHP (Hypertext Preprocessor) is a scripting language commonly used for web development. The PHP language was originally a CGI scripting language written in C language by Rasmus Lerdorf. Since then, PHP has been a scripting language used for web development. This article will compare the differences between PHP and C languages, allowing us to better understand PHP and how to use it.

1. Syntax difference

C language is a compiled language, while PHP is an interpreted language. C language code must be compiled by a compiler before it can be run, while PHP code only needs to be interpreted and executed on the server. Syntactically, the PHP language is simpler, more intuitive, and easier to learn than the C language. Some C language syntax also exists in PHP, but usually in a more concise form.

2. Data types

C language has many basic data types, such as int, float, double, char, etc. PHP contains more data types, including strings, arrays, objects, resources, etc. In addition, PHP also has automatic type conversion features.

3. The difference between functions and libraries

The PHP language contains a large number of built-in functions and libraries, making it a powerful web development language. These functions and libraries often make it easier to write code and avoid the complexity of writing custom functions. For C language, using functions and libraries requires first including the corresponding header files, which is more troublesome when writing code.

4. Object-oriented programming

The C language can be written in an object-oriented form, but this usually requires more code writing and higher complexity. PHP can easily adopt object-oriented programming, and the creation and use of classes and objects are very convenient. This makes the PHP language more flexible and easier to maintain than the C language.

5. Server-side scripting language

PHP language is a powerful web server-side language that can easily reference other HTML and CSS files and add them to the page Embed the script directly and the output of the script is sent to the user's web browser as a result. However, C language is a system-level language and cannot be used directly on the Web.

In general, PHP and C language have their own advantages and disadvantages, and they are languages ​​used in different scenarios. For web development, PHP is undoubtedly a better choice. It has more built-in functions and libraries, making it easier to write and maintain web applications.

Before learning PHP, having a foundation in C or another programming language will be helpful, but is not required. PHP language is easy to learn and more beginner-friendly. In today's web development, proficiency in the PHP language is very necessary.
