Example 2: basic code for file upload in php
//This is the minimal code for an image upload for first time learners
//html portion
<!DOCTYPE html>
<html>
<head>
<title>ImageUpload</title>
</head>
<body>
<form action="upload.php" method="post" enctype="multipart/form-data">
<label>Username</label>

$user=$_POST['username'];
$image=$_FILES['myfile'];
echo "Hello $user <br/>";
echo "File Name<b>::</b> ".$image['name'];

Example 3: php image upload in database
<?php
error_reporting(0);

$db = mysqli_connect("localhost", "root", "", "image_upload");
// Get all the submitted data from the form
$sql = "INSERT INTO images (filename) VALUES ('$filename')";
// Execute query
mysqli_query($db, $sql);
// Now let's move the uploaded image into the folder: image
if (move_uploaded_file($tempname, $folder)) {
$msg = "Image uploaded successfully";
}else{
$msg = "Failed to upload image";
}
}
$result = mysqli_query($db, "SELECT * FROM images");
