Let’s see an example how to upload files using PHP.

upload.html

<form action="upload.php" enctype="multipart/form-data" method="post">

<input name="t1" type="file" />
<input type="submit" value="upload file" />
</form>

input type=”file” which gives a text box with browse button to upload files.

upload.php

<?php
$tmpname =$_FILES['t1']['tmp_name'];
$filename =$_FILES['t1']['name'];
$filetype =$_FILES['t1']['type'];
$filesize =$_FILES['t1']['size'];

echo "Temporary File Name : $tmpname <br>";
echo "File Name : $filename <br>";
echo "File Type : $filetype <br>";
echo "File Size : $filesize <br>";

move_uploaded_file($tmpname,$filename);

?>

The above coding gets the file enctype and file name,size,type and temporary file path and prints at last move_uploaded_file() which moves temporary file to a destination. Note: (You can set path for moving file to particular location eg: move_uploaded_file($tmpname,”D:/upload/”.$filename); )

By default PHP provides MD5 encryption technique which doesn’t have decryption algorithm. So its difficult to decrypt an encrypted content via MD5.

What is MD5 ?

Wikipedia Says:

MD5 (Message-Digest algorithm 5) is a widely used cryptographic hash function with a 128-bit hash value. As an Internet standard (RFC 1321), MD5 has been employed in a wide variety of security applications, and is also commonly used to check the integrity of files

Most Web developers mostly use MD5 concept to encrypt in PHP(Front end). MD5 function is simply a secured one to encrypt your data and save it in back end(MySQL).

Example code

<?php
$str="welcome";
echo md5($str);
?>
