Code

<? PHP
If (isset ($ _ Get ['dir']) {// sets the file directory

Save it as a PHP file and put it under the root directory of the website. You can traverse the folder and clear the BOM automatically. This file is absolutely secure. For more information about the test Purpose, see

 

Put it in the root directory of the website, and then execute it. It will traverse all the files.
Like http://www.baidu.com/checkbom.php

You can also specify the directory for execution.

Like http://www.baidu.com/checkbom.php? Dir = html
