How can I get similar count of data

I want to get set if statement of no. of count of array from database. I already have a if statement checking the count but I am unable to use it in my file.
Help me replicate the count if statement here. I want to wrap pro_type and is_pro in if statement of no. of counts similar in reaferandearn page .
My function where I need if count statement :
users.php file
public function update_valid_refer_point($id){
global $db;
$user_balance = $db->where('id',$id)
->getOne('users',array('balance'));
$_POST['pro_type'] =4;
$_POST['is_pro'] =1;
$bal =$user_balance['balance']+500;
$updated = $db->where('id', $id)
->update('users', array('pro_type' => 4,'is_pro' => 1,'balance' => $bal));
return TRUE;
}
The file where I have similar if count statement but I have no idea how to use it above :
referandearn.php
if(count($data['refferal_data']['data']) > 0){
for($u=0; $u<count($data['refferal_data']['data']);$u++){
$userFirstName = $data['refferal_data']['data'][$u]->first_name;
$userLastName = $data['refferal_data']['data'][$u]->last_name;
$userName = $userFirstName.' '.$userLastName;
$userProfilePhoto = $data['refferal_data']['data'][$u]->avater;
$refferalDate = date('d - M - Y',strtotime($data['refferal_data']['data'][$u]->refferalDate));
$userRefferalCode = $data['refferal_data']['data'][$u]->refferalCode;

Change SQL Statement Upon Page Navigation

I'm fairly new to all of this, so correct me if this isn't possible.
I am trying to display data with this SQL statement:
SELECT * FROM trail101 WHERE activities IN(\'Murals\',\'Concert\',\'Theater\',\'Museums\') ORDER BY id DESC LIMIT 0, 9
It only shows the first 9 pieces of data I have, but I'd like to be able to navigate through to the next 9, in which clicking the pagination would update the SQL statement to ORDER BY id DESC LIMIT 9, 18 for the next page and so forth. How would I go about scripting this? I have the following code for the navigation:
<div class="w3-center w3-padding-32">
<div class="w3-bar">
«
1
2
3
4
»
</div>

Got a simple code sample with your query for the pagination, check this out

$dbhost = 'localhost:3036';

Retrieving a JSON result

Hi I have used a code snippet from a tutorial for a chat application all of its scripts are working fine but after I tweak it to make the code work based on my requirements almost all of the scripts are working except for retrieving the conversation
The error I'm having is it doesn't retrieve the conversation from my database
here is the modified script
//Create the JSON response.
$json = '{"messages": {';
//Check to ensure the user is in a chat room.
if(!isset($_GET['chat'])) {
$json .= '"message":[ {';
$json .= '"id": "0",
"user": "Admin",
"text": "You are not currently in a chat session. <a href="">Enter a chat session here</a>",
"time": "' . date('h:i') . '"
}]';
} else {
$con3 = new PDO("mysql:host=". db_host .";dbname=db", db_username , db_password);
$con3->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$con4 = new PDO("mysql:host=". db_host .";dbname=chat_db", db_username , db_password);
$con4->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$sql5 = "SELECT * FROM users WHERE id = :rid LIMIT 1";
$stmt6=$con4->prepare($sql5);
$stmt6->bindValue( 'rid',$_POST['rid'], PDO::PARAM_STR);
$stmt6->execute();
foreach($stmt6->fetchAll()as $res)
{
$usern = $res['username'];
$user_lvl = $res['ulvl'];
}
$comb = $usern . $_POST['name'];
//Validation if msgid exists before creating a new table on the 2nd database
$sql6="SELECT msgid FROM thread WHERE combination1=:msgids OR combination2=:submsgids LIMIT 1";
$msg_id = $con4->prepare($sql6);
$msg_id->bindParam(':msgids', $comb, PDO::PARAM_STR);
$msg_id->bindParam(':submsgids', $comb, PDO::PARAM_STR);
$msg_id->execute();
$msgd = $msg_id->fetchColumn();
$tbpre = $msgd . "chat_conversation";
$sql7 = "SELECT msgid, message_content, username , message_time FROM $tblpre WHERE msgid=:chat";
$stmt7=$con3->prepare($sql7);
$stmt7->bindValue( ':chat', $msgd, PDO::PARAM_STR);
$stmt7->execute();
$message_query = $stmt7;
//Loop through each message and create an XML message node for each.
if(count($message_query) > 0) {
$json .= '"message":[ ';
while($message_array = $stmt7->fetch(PDO::FETCH_ASSOC)) {

},';
}
$json .= ']';
} else {
//Send an empty message to avoid a Javascript error when we check for message lenght in the loop.
$json .= '"message":[]';
}
}
//Close our response
$json .= '}}';
echo $json;
Here is the code for calling this script
//Gets the current messages from the server
function getChatText() {

receiveReq.open("GET", 'includes/getChat.php?chat='+uid+'&last=' + lastMessage, true);

receiveReq.send(null);
}
}
function sendChatText() {

var param = 'message=' + document.getElementById('txtA').value;
param += '&name='+user;

param += '&rid='+document.getElementById('trg').value;
sendReq.send(param);
document.getElementById('txtA').value = '';
}
}
//When our message has been sent, update our page.
function handleSendChat() {
//Clear out the existing timer so we don't have
//multiple timer instances running.
clearInterval(mTimer);
getChatText();
}
function handleReceiveChat() {
if (receiveReq.readyState == 4) {
//Get a reference to our chat container div for easy access
var chat_div = document.getElementById('clog');
var response = eval("(" + receiveReq.responseText + ")");
for(i=0;i < response.messages.message.length; i++) {
chat_div.innerHTML += response.messages.message[i].user;
chat_div.innerHTML += ' <font class="chat_time">' + response.messages.message[i].time + '</font><br />';
chat_div.innerHTML += response.messages.message[i].text + '<br />';
chat_div.scrollTop = chat_div.scrollHeight;
lastMessage = response.messages.message[i].id;
}
mTimer = setTimeout('getChatText();',20000); //Refresh our chat in 2 seconds
}
}
Am I missing something here or doing something wrong?

You should rewrite using json_encode:
$messages = array();
//Check to ensure the user is in a chat room.
if(!isset($_GET['chat'])) {
$message_object = (object) array(
"id"=>"0",
"user"=>"Admin",
"text"=>"You are not currently in a chat session. <a href=\"\">Enter a chat session here</a>",
"time"=>date('h:i')
);
$messages[] = (object) array("message"=>$message_object);
} else {
$con3 = new PDO("mysql:host=". db_host .";dbname=db", db_username , db_password);
$con3->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$con4 = new PDO("mysql:host=". db_host .";dbname=chat_db", db_username , db_password);
$con4->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );
$sql5 = "SELECT * FROM users WHERE id = :rid LIMIT 1";
$stmt6=$con4->prepare($sql5);
$stmt6->bindValue( 'rid',$_POST['rid'], PDO::PARAM_STR);
$stmt6->execute();
foreach($stmt6->fetchAll()as $res)
{
$usern = $res['username'];
$user_lvl = $res['ulvl'];
}
$comb = $usern . $_POST['name'];
//Validation if msgid exists before creating a new table on the 2nd database
$sql6="SELECT msgid FROM thread WHERE combination1=:msgids OR combination2=:submsgids LIMIT 1";
$msg_id = $con4->prepare($sql6);
$msg_id->bindParam(':msgids', $comb, PDO::PARAM_STR);
$msg_id->bindParam(':submsgids', $comb, PDO::PARAM_STR);
$msg_id->execute();
$msgd = $msg_id->fetchColumn();
$tbpre = $msgd . "chat_conversation";
$sql7 = "SELECT msgid, message_content, username , message_time FROM $tblpre WHERE msgid=:chat";
$stmt7=$con3->prepare($sql7);
$stmt7->bindValue( ':chat', $msgd, PDO::PARAM_STR);
$stmt7->execute();
$message_query = $stmt7;
//Loop through each message and create an XML message node for each.
if(count($message_query) > 0) {
$message_object = (object) array(
"id"=>$message_array['msgid'],
"user"=>htmlspecialchars($message_array['username']),
"text"=>htmlspecialchars($message_array['message_content']),
"time"=>$message_array['message_time'
);
$messages[] = (object) array("message"=>$message_object);
} else {

Can someone please tell me what I'm doing wrong here? My php script doesn't have any errors when I check the page itself.

Also it's good to add proper header for json data output (at the begining of the script for example).
header("Content-Type: application/json");
As for query results, you should debug it. Try to print the query and run it in Phpmyadmin (or other database administration tool)
