Utilizing Ajax, PHP, and jQuery to Dynamically Update DIV Content
In this guide, we'll explore the process of dynamically changing the content of a DIV element using Ajax, PHP, and jQuery.
When a user clicks on a link, the script makes an Ajax call using the link's URL as a data parameter to your PHP file. The PHP file then processes the data and returns it as a string. Finally, the string is used to replace the content of the targeted DIV.
To implement this functionality, follow these steps:
<script>
function getSummary(id) {
$.ajax({
type: "GET",
url: 'Your URL',
data: "id=" + id, // appears as $_GET['id'] on the server-side
success: function(data) {
// data is your summary
$('#summary').html(data);
}
});
}
</script>
Next, add an onclick event to your list items:
<a onclick="getSummary('1')">View Text</a>
<div id="summary">This text will be replaced when the onclick event is triggered.</div>
By following these steps, you can dynamically update the contents of a DIV with data retrieved from your PHP file using Ajax and jQuery's manipulation capabilities.

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.
