conn.php.
<?php
if(!$conn){
die("Error: Failed to connect to database!"); }
?>

index.php.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1" />
<link rel="stylesheet" type="text/css" href="css/bootstrap.css" />
</head>
<body>
<nav class="navbar navbar-default">
<div class="container-fluid">
<a class="navbar-brand" href="https://sourcecodester.com">Sourceodester</a>
</div>
</nav>
<div class="col-md-3"></div>
<div class="col-md-6 well">
<h3 class="text-primary">PHP - Random Image Display In MySQLi</h3>
<hr style="border-top:1px dotted #ccc;"/>
<div class="col-md-4">
<form method="POST" action="upload.php" enctype="multipart/form-data">
<div class="form-group">
<label>Image:</label>
<input type="file" name="image" class="form-control" required="required"/>
</div>
<center><button class="btn btn-primary" name="upload"><span class="glyphicon glyphicon-save"></span> Upload</button></center>
</form>
</div>
<div class="col-md-8">
<?php include 'image_display.php'?>
</div>
</div>
</body>
</html>

This code contains the php query of the application. This code will upload the image file to the database server. To do that just copy and write this block of codes inside the text editor, then save it as
upload.php.
<?php
require_once 'conn.php';
if(ISSET($_POST['upload'])){ $image_name = $_FILES['image']['name'];
$image_temp = $_FILES['image']['tmp_name'];
$path = "upload/".$name;
$allowed_ext = array("gif", "jpg", "jpeg", "png"); echo "<script>alert('Image saved!')</script>";
header("location: index.php"); }
}else{
echo "<script>alert('Image only')</script>";
}
}
?>

image_display.php
<div class="col-md-12">
<?php
require 'conn.php';
?>
<img src="<?php echo $fetch['location']?>" style="margin:10px; float:left;" height="150" width="150"/>
