Simple File Upload with PHP

In this post I am going to show you how to upload file to server using simple PHP and HTML code. Uploading files with php is one of the most fundamental programming skill. This script will allow you to upload single image file and store it to the specified directory to the server for later usage.

Source: 

<?php
valid_formats = array("jpg","jpeg","JPG", "png", "gif", "bmp");
$max_file_size = 1024*1024*1024;
$dir = "uploads/";

// If File Submitted
if($_SERVER['REQUEST_METHOD'] == "POST"){
	$ext = pathinfo($_FILES['file']['name'], PATHINFO_EXTENSION);
	if ( in_array($ext, $valid_formats)) {
		if( $_FILES['file']['size'] < $max_file_size ){
			$uniq = base_convert(uniqid(), 16, 10);
			$tmp = $_FILES['file']['tmp_name'];
			$uniq_file_name = $uniq.".".$ext;
			if(move_uploaded_file($tmp, $dir.$uniq_file_name)){
				$query = mysql_query("INSERT INTO files (id, file) VALUES (null, '{$uniq_file_name}')");
				$msg = "Uploading successful!";
			}
			else{
				$msg = "Problem while moving file";
			}
		}
		else{
			$msg = "File is too large";
		}
	}
	else{
		$msg = "Worng file format";
	}
}
?>

<body>
<?php
//Show message
if(isset($msg)){
	echo "<p>{$msg}</p>\n";
}
?>
<form action="" method="POST" enctype="multipart/form-data">
	<label for="file">File:</label>
	<input type="file" name="file" id="file" /> 
	<br />
	<input type="submit" name="submit" value="Submit" />
</form>
</body>
</html>
If we look over the script we can see that there is two separate part in this script. First one is the PHP and the second one is HTML form. HTML form will allow you to upload file using web browser and the PHP code will catch your uploaded file into the server. It will look up the  validation of your upload, give it a unique name and store it to your defined directory,
