Win7 changing file types PHP file header-based document type validation class function

I've written a validation class here that uses the file header to determine the file format. (also not completely secure, if the user forged the file header, can also be verified)

Copy the Code code as follows:

/**
* Type of document to be checked
*
* @author Silver
*/
Class Filetypevalidation
{
File types, different header information

Call

Copy the Code code as follows:

Require './class_filetypevalidation.php ';
File path
$filePath = "D:/test.png";
$x = Filetypevalidation::validation ($filePath, ' zip ');
Var_dump ($x);

The above describes the win7 change file type PHP file header-based file type validation class functions, including the Win7 change the file type aspect of the content, I hope to be interested in PHP tutorial friends helpful.
