Dynamically Updating DIV Content via AJAX, PHP, and jQuery
Question: How can you dynamically update the content of a DIV element using AJAX, PHP, and jQuery, where each link click retrieves data from the database and replaces the DIV with the fetched summary?
Answer:
Step 1: Create the HTML Structure
- Include the DIV element that will display the summary:
<code class="html"><div id="summary"></div></code>
- Add a list of links that trigger the summary retrieval process:
<code class="html"><a href="?id=1" class="movie">Name of movie</a> <a href="?id=2" class="movie">Name of movie</a></code>
Step 2: Implement the jQuery Script
- Create a jQuery function to handle the AJAX request and update the DIV:
<code class="javascript"><script>
function getSummary(id) {
$.ajax({
type: "GET",
url: 'Your URL',
data: "id=" + id, // appears as $_GET['id'] @ your backend side
success: function(data) {
// data is your summary
$('#summary').html(data);
}
});
}
</script></code>
Step 3: Add Click Event to Links
- Add an onclick event to each link, passing the corresponding ID:
<code class="html"><a onclick="getSummary('1')">View Text</a></code>
Step 4: Server-Side PHP
- In the PHP script at the URL specified in $.ajax(), retrieve the summary based on the received ID:
<code class="php">$id = $_GET['id']; $summary = fetchSummary($id); // Fetch summary from database</code>
- Return the fetched summary as a string:
<code class="php">echo $summary;</code>
By clicking the links, the jQuery function will trigger AJAX requests, fetch the summary from the PHP script, and update the DIV with the retrieved content.

How do I destroy a session in PHP using session_destroy()?
Jun 20, 2025 am 01:06 AM
To completely destroy a session in PHP, you must first call session_start() to start the session, and then call session_destroy() to delete all session data. 1. First use session_start() to ensure that the session has started; 2. Then call session_destroy() to clear the session data; 3. Optional but recommended: manually unset$_SESSION array to clear global variables; 4. At the same time, delete session cookies to prevent the user from retaining the session state; 5. Finally, pay attention to redirecting the user after destruction, and avoid reusing the session variables immediately, otherwise the session needs to be restarted. Doing this will ensure that the user completely exits the system without leaving any residual information.
