In today's digital online world, HTML (HyperText Markup Language) and PHP ( Hypertext Preprocessor) are two vital technologies that play a vital role in building web pages and enabling dynamic features.
HTML is a markup language used to create the basic framework for the structure and content of web pages. HTML implements the function of presenting text, pictures, links and other content in the browser through the organizational structure of tags and attributes. A simple HTML page consists of the declaration, tag,
tag and tag. The tag is used to define the title and metadata of the web page, and < The ;body> tag contains the actual content of the web page.Here is a basic HTML code example that shows how to create a simple web page with headings and paragraphs:
1 2 3 4 5 6 7 8 9 10 |
|
PHP is a server-side scripting language used to create dynamic web content and interactivity. Unlike static HTML, PHP allows content to be dynamically generated based on conditions and data when the web page loads. By combining with the database, PHP can also implement functions such as user login, data submission, and content management.
The following is a simple PHP code example that shows how to output the current time and the user's IP address in a web page:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
|
In the above code, the PHP code is embedded in HTML, using the <?php ... ?>
tag to identify the PHP code segment. By calling the date()
function to obtain the current time, and using $_SERVER['REMOTE_ADDR']
to obtain the user's IP address, the function of dynamically generating content is realized.
In general, HTML and PHP perform their respective duties in the online world. HTML is responsible for the static content presentation and structural layout of the page, while PHP is responsible for handling dynamic content generation and user interaction. Understanding the positioning and role of these two technologies will help developers better build powerful and interactive websites and network applications.
