How to read database in html

Reading the database using HTML

HTML (Hypertext Markup Language) itself cannot interact directly with the database. To implement database operations in HTML, you need to use a back-end programming language, such as PHP, Python, or Java, and embed these back-end scripts in HTML.

The following is how to use HTML with a back-end language to read the database:

1. Connect to the database

Usemysqli_connect in PHP ()Function establishes a connection with the database.

2. Execute the query

Use themysqli_query()function to execute the SQL query to obtain the data.

3. Processing results

Use themysqli_fetch_array()ormysqli_fetch_assoc()function to obtain data rows from the query results .

4. Display data in HTML

Use HTML elements (such as tables, lists, or paragraphs) to display data obtained from the database in an HTML document.

Code sample (PHP):

   用户名: " . $row['username'] . "

"; echo "

电子邮件: " . $row['email'] . "

"; } // 关闭数据库连接 mysqli_close($conn); ?>
Copy after login

Additional information:

  • ##mysqli# for PHP ## The module provides functions for interacting with the MySQL database.Other backend languages also provide libraries for interacting with various databases.
