I am currently creating a stock market simulation and am working on the moment that the user logs into the simulation. I have a PHP script that will generate a certain price for a company four times and update it into my MySQL database while running. I currently have the following code:
PHP:
if (isset($_SESSION['userId']))
{
$isPlaying = 0;
while ($isPlaying <= 3)
{
$priceTemp = (rand(3300, 3700) / 100);
$sql = "UPDATE pricestemp SET price = $priceTemp WHERE companyName = 'Bawden';";
mysqli_query($conn, $sql);
sleep(1);
$isPlaying++;
}
echo '<h1>Welcome to the simulation</h1>';
}
I am aiming for these updates to happen in the background once the user has logged into the simulation. When refreshing my database every second, the updated prices are shown which is one of my objectives. However, what I would like it to do is still load the HTML onto the page (to say "Welcome to the simulation") while updating the database with every second with an updated price.
So far, when I log in, I have to wait 4 seconds before the HTML will load. In the future, I hope to have it consisently updating until a certain condition is met but when I have set an infinite loop earlier the HTML never loaded.
What do I have to do to allow the HTML to load once logged in and have the prices being generated and updated in the MySQL database in the background with no delay in either of these tasks happening?
