The following code uses PHP to remove the BOM information of all files in the current directory and sub-directories, create a file, put it under the root directory, and then access the file through a browser.
Example
Save the above code as a php file and put it in the directory where the bom needs to be removed, and then run the php file, check the bom of the Directory and all the files in the subdirectories of the Directory and remove the bom.
