Example 3: 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>
		<input type="text" name="username">
		<br>
		<label>UploadImage</label>
		<input type="file" name='myfile'>
		<br/>
		<input type="submit" value="upload">
	</form>
</body>
</html>
  
 //php portion
  <?php
	$user=$_POST['username'];
	$image=$_FILES['myfile'];
	echo "Hello $user <br/>";
	echo "File Name<b>::</b> ".$image['name'];

	move_uploaded_file($image['tmp_name'],"photos/".$image['name']);
	//here the "photos" folder is in same folder as the upload.php, 
	//otherwise complete url has to be mentioned
	?>

Example 4: php image upload in database

<?php
error_reporting(0);
?>
<?php
$msg = "";

// If upload button is clicked ...
if (isset($_POST['upload'])) {

	$filename = $_FILES["uploadfile"]["name"];
	$tempname = $_FILES["uploadfile"]["tmp_name"];
		$folder = "image/".$filename;

	$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");
?>

<!DOCTYPE html>
<html>
<head>
<title>Image Upload</title>
<link rel="stylesheet" type= "text/css" href ="style.css"/>
<div id="content">

<form method="POST" action="" enctype="multipart/form-data">

      $f_ext   = strtolower(end(explode('.',$f_name_2)));
      $f_rename = $_SESSION['uid'] . "." . $f_ext;

        if($f_error == 0 && in_array($f_ext, $f_ext_allowed) 
        && $f_size < $f_maxsize && mb_strlen($f_name_2, "UTF-8") < 225 
        && preg_match("`^[-0-9A-Z_\.]+$`i", $f_name_2)){
