Dynamic content updating without page refresh: PHP and MySQL solution

I’m working on a project where I need to update specific parts of a webpage without reloading the entire page. I’ve seen this done on other sites, where certain elements refresh automatically. For example, I noticed a battle page on an online game that updates fight stats in real-time. The cool thing is, it only refreshes small sections of the page, not the whole thing. I tried using jQuery, but it only updates the HTML. What I really need is to refresh data from my MySQL database through PHP. Is this even doable? If so, how can I achieve this effect? I’m pretty new to web development, so any tips or code snippets would be super helpful. Thanks in advance for any advice!

hey, ajax idea is rad. i’ve always found it kinda nifty for partial updates. how bout da data refresh freq? have u tried setInterval or websockets? what do you think?

Absolutely, dynamic content updating without page refresh is achievable using AJAX (Asynchronous JavaScript and XML). Here’s a brief overview of how you can implement this:

  1. Set up a PHP script that queries your MySQL database and returns the updated data.

  2. Use JavaScript to make periodic AJAX calls to this PHP script.

  3. When the AJAX call receives a response, update the relevant parts of your HTML with the new data.

For optimal performance, consider using JSON for data transfer between PHP and JavaScript. Also, be mindful of your update frequency to avoid unnecessary server load.

If you need real-time updates, WebSockets might be a more suitable option, though they’re more complex to implement. Hope this helps point you in the right direction!

yo, have u considered using fetch api? it’s pretty sweet for ajax stuff. u can grab data from ur php script n update ur page without a full reload. just gotta set up an endpoint that spits out json, then use js to fetch n update. it’s not too hard once u get the hang of it!
