How to Populate an HTML Dropdown List with Data from a MySQL Database
To dynamically populate an HTML dropdown list with data retrieved from a MySQL database, follow these steps:
- Execute an SQL query to fetch the needed data from the database. The query should return data in a suitable format for populating the dropdown list.
- Loop through the rows returned by the query. For each row, create an HTML option element with the relevant data from the row. The value attribute of the option element should hold the unique identifier for the record, while the visible text inside the option should represent the display value.
- Append the generated option elements to the HTML dropdown list.
An example code using PDO to achieve this:
<code class="php">// Assume $db is a PDO object
$query = $db->query("SELECT id, name FROM agents"); // Run your query
echo '<select name="agents">'; // Open your drop down box
// Loop through the query results, outputing the options one by one
while ($row = $query->fetch(PDO::FETCH_ASSOC)) {
echo '<option value="'.$row['id'].'">'.$row['name'].'</option>';
}
echo '</select>';// Close your drop down box</code>
By following these steps, you can populate your HTML dropdown list with data retrieved from your MySQL database, ensuring that newly added agents are automatically available as options in the dropdown.

What are the best practices for writing clean and maintainable PHP code?
Jun 24, 2025 am 12:53 AM
The key to writing clean and easy-to-maintain PHP code lies in clear naming, following standards, reasonable structure, making good use of comments and testability. 1. Use clear variables, functions and class names, such as $userData and calculateTotalPrice(); 2. Follow the PSR-12 standard unified code style; 3. Split the code structure according to responsibilities, and organize it using MVC or Laravel-style catalogs; 4. Avoid noodles-style code and split the logic into small functions with a single responsibility; 5. Add comments at key points and write interface documents to clarify parameters, return values ??and exceptions; 6. Improve testability, adopt dependency injection, reduce global state and static methods. These practices improve code quality, collaboration efficiency and post-maintenance ease.

How do I embed PHP code in an HTML file?
Jun 22, 2025 am 01:00 AM
You can embed PHP code into HTML files, but make sure that the file has an extension of .php so that the server can parse it correctly. Use standard tags to wrap PHP code, insert dynamic content anywhere in HTML. In addition, you can switch PHP and HTML multiple times in the same file to realize dynamic functions such as conditional rendering. Be sure to pay attention to the server configuration and syntax correctness to avoid problems caused by short labels, quotation mark errors or omitted end labels.
