I’m trying to find a good example on how to retrieve records using PHP from a table and refresh it say every 2 minutes using Ajax.

Anyone can point me to that tutorial?

    I don’t think you’ll find a tutorial that specific, but you just need to learn AJAX and then make the AJAX call every two minutes using JavaScript’s setInterval method.

    EDIT

    Meh, I’m bored enough to write this example. This isn’t tested, but I don’t think it has errors.

    <html>
<head>
    <script type="text/JavaScript">
        window.onload = function()
        {
            // call your AJAX function every 2 minutes (120000 milliseconds)
            setInterval("getRecords()", 120000);
        };

        function getRecords()
        {
            // create the AJAX variable
            var xmlhttp;
            if (window.XMLHttpRequest)
                xmlhttp = new XMLHttpRequest();
            else
                xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

            // set up the response function
            xmlhttp.onreadystatechange = function()
            {
                if (xmlhttp.readyState == 4 && xmlhttp.status == 200)
                {
                    /*
                        Your code goes here. 'xmlhttp.responseText' has the output from getRecords.php
                    */
                    document.getElementById("txaRecords").innerHTML = xmlhttp.responseText;
                }
            }

            // make the AJAX call
            xmlhttp.open("GET", "getRecords.php", true);
            xmlhttp.send();
        }
    </script>
</head>
<body>
    <textarea id="txaRecords"></textArea>
</body>
</html>
