I have an application to list the information via JSON db, I can list the information from db, the problem is that it comes without the layout of jQuery Mobile, could someone give me some light on how to solve this problem?
Below is my code:

If I understand your question correctly, you are able to return json full of data you want and display it in #result but the style doesn't have the jQuery Mobile style applied. If this is a correct summation
First, add an id to your listview element
<ul id="mylistview" data-role="listview" data-inset="true">
then add this line after $("#result").html(data);
$( "#mylistview" ).listview( "refresh" );
See the Listview Widget page for more on listviews.

I want to make a like system and this is what I have so far. I can't figure out how to make it only increment once can anyone help me out? I feel like i might have to use session variables but im not sure.

?>
Also just to let you know, I already have session variables established ie. $_SESSION['user_id'] and `$_SESSION['username']
Since you already have a user_id, I'll assume you have a users table.
You could create a new table with meme_vote_id and user_id columns, and a unique index using both fields:
CREATE TABLE `meme_voters` (
`meme_vote_id` INT UNSIGNED NOT NULL,
`user_id` INT UNSIGNED NOT NULL,
UNIQUE INDEX `unique_voter` (`meme_vote_id`, `user_id`)
);
Then when someone votes:
$sql = mysqli_query($con,"SELECT COUNT(*) AS count FROM meme_voters WHERE meme_vote_id={$id} AND user_id={$_SESSION['user_id']}" );
$rs = mysqli_fetch_object($sql);
if ( $rs->count == 0 ) {
$sql = "INSERT INTO meme_voters (meme_vote_id, user_id) VALUES ({$id}, {$_SESSION['user_id']})";
mysqli_query($con, $sql);
$sql = "UPDATE meme_vote SET vote=vote+1 WHERE id=$id";
$res = mysqli_query($con, $sql);

I'm building a two-way chat application that stores messages into a MySQL database. I would like to use Server Sent Events and have the PHP and HTML all in one page but the problem I'm facing is that the header cannot be set to text/event-stream or I will break the HTML.
My question is how can I have the PHP, JS and HTML on the same page when using Server Sent Events?
Here is my opening JS. I set the EventSource to index.php even though this might be wrong.
<html>

<script>
if(typeof(EventSource) !== "undefined") {
var source = new EventSource("index.php");
source.onmessage = function(event) {
document.getElementsByClassName("message").innerHTML = event.data;
};
}else {
document.getElementsByClassName("message").innerHTML = "Sorry, your browser does not support server-sent events...";
}
</script>
<h1>LoRa Chat</h1>
<?php
$SSE = (#$_SERVER["HTTP_ACCEPT"] == "text/event-stream");
if($SSE){
header('Cache-Control: no-cache');
header("Content-Type: text/event-stream");
}
else {
header("Content-Type: text/html");
}
//Database Stuff
$connect = mysqli_connect('localhost', 'user', 'Pass');
mysqli_select_db($connect,"allmessages");
$sql = "SELECT *, if(mymessages > yourmessages, mymessages, yourmessages) FROM lora_messages";
$results = mysqli_query($connect, $sql);
while($row = mysqli_fetch_array($results)) {
if ($row ['mymessages'] > $row ['yourmessages']){
?>
<div class='chat'>
<div class='mine messages'>
<div class='message'>
<?php echo "data: ".$row['mymessages']; flush();?>
</div>

elseif ($row ['mymessages'] < $row ['yourmessages']){

</html>
EDIT: I have tried separating the PHP the HTML and put the PHP logical part outside the HTML. I'm able to get Server Sent Events via inspector in Chrome but not sure how to loop through the DB entries in JS. I'm not comfortable with JS syntax.

$recieve = $_GET['yourmessage'];
$recievemsg = "INSERT INTO lora_messages (mymessages, yourmessages) VALUES ('', '".$recieve."')";
}

If your after it being in one file you just need the one outer if statement which separates the two logical parts.
<?php
if ($_SERVER["HTTP_ACCEPT"] === 'text/event-stream') {
// event stream code
...
while (true) {
...
} else {
// client side code
?>
<head>
<meta name="viewport" content="w
...
<?php }
You cant intertwine the two parts like your doing:
<div class='message'>
<?php echo "data: $row['mymessages']"; flush();?>
</div>
Your serverside part is incomplete but that's beyond the scope of the question,ive commented with a link to a working example.

I have this PHP and jQuery code which works in coalition with my database. This is the only page. The code runs and gives me a row of data, but when I click the collapse button it only works for the first row. Even if I click any other row, that action affects only the first row and all the other rows collapse, which is useless.
How do I make it so that all rows work? It's like the button is doubled and only works for the first row.

This is using css, html(+php to create row), and native javascript.
The idea is to assign an unique for each row.
others are quite self explanatory, hope this helps.
to anyone coming in here in search of sql data display with accordian collapse. here Qid is my tables auto incremented value. AS_Questions is my table name. db is my database name.

I have a page (index.php) which has a login form. When a user logs in, it checks the credentials and if correct, creates a session, sets two variables, auth to yes and user to the username, and redirects to another page(pihome.php) via echoing a javascript window.location.href command. This is where the problem starts. On this page if I run session_start() it used to say session has already been created, ignoring but I was able to access the variables from the previous page. Now using an if condition with session_status() it session_start() works. I have a Logout button on this page which goes to another page (Logout.php). On that page when I try to run session_destroy() it says a session has not been started and when I try to echo the variables it says they have not been defined.
While browsing SO for solutions I saw certain solutions that applied to variables not being carried over but I can access them on the pihome.php page but logout.php doesn't let me access them or execute session_destroy(). I would like to know if I'm using the sessions correctly and if I should place session_start() at the beginning of every page and how to correctly access the variables. Thanks!
