this will help The call is asynchronous. After you call send, the call begins in the background. In the meantime, getNewUploads returns. Later, the function you've assigned is called with the answer. When you do return xmlhttp.responseText, you're returning from this anonymous function (assigned to onreadystatechange), not from getNewUploads (which is already done).
You can use a callback instead. Something like:
code :
function getNewUploads(callback) {
    if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
       xmlhttp=new XMLHttpRequest();
    else {// code for IE6, IE5
       xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    xmlhttp.onreadystatechange=function() {
       if (xmlhttp.readyState==4 && xmlhttp.status==200) {

function show_tab(tab_id) {
    if(tab_id == "#tab_2") {
      getNewUploads(function(data_string) {
        var so = new SWFObject(".....");          
        so.addVariable("theDataString", data_string);

wish of those help Javascript cannot talk to MySQL directly. You can, however, set up an AJAX service as an intermediary - have Javascript talk to this service, the service talks to MySQL, and then returns the query results.
You can roll your own AJAX handlers in Javascript, but it's far easier to use a premade one, such as provided by jQuery. The server-side handler would be (typically) written in something like PHP, Perl, Ruby, etc...

Hope this helps The select() method returns an array. You need to collect() the array and then call toJson():
code :
<script type="text/javascript">
    $(document).ready(function() {
        $('#userTable').DataTable( {
            "scrollX": true,
            "scrollY": '55vh',
            "scrollCollapse": true,
            "paging": false,
            dom: 'ft',
            "aaData": {!! collect($users)->toJson() !!},
            "aoColumns": [
                { "sTitle": "Name",   "mData": "name" },
                { "sTitle": "Email",  "mData": "email" },
        } );
    } );

This might help you First, you need to create one PHP file and move your PHP payout() in php file. second, you need to ajax call in the javascript interval.
code :
//add the following code after your connection object
function payout(){
    $sql = $conn->query("UPDATE wallets SET balance = balance - 1 WHERE wallet = '$wallet' " );
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,"https://faucethub.io/api/v1/send");
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS,
            "api_key=$apikey&to=$wallet&currency=$shortcurrency&amount=$doge ");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $server_output = curl_exec ($ch);
    curl_close ($ch);
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button onclick="send()" class="btn-success"><i class="fas fa-exclamation-circle"></i> Claim <i class="fas fa-exclamation-circle"></i></button>
function send() {
	setInterval(function () {
			type: 'POST',
			url: 'payout.php',
			success: function (data) {
				console.log("payout attempt");
	}, 3000);
