I write a validation class here that uses the file header to determine the file format. (also not completely safe, if the user forged the file header, can also pass validation)
Copy Code code as follows:
<?php
/**
* Type of document to be verified
*
* @author Silver
*/
Class Filetypevalidation
{
File type, different header information
