Quickly remove the BOM method in the whole site program file encoding-PHP source code

The BOM method in the whole station program file encoding is quickly removed. Today, it is found that this method is also sometimes. after The Independent ip space is purchased on the hosts, the website program specified by the device will be logged on to the background after the device is completed, the verification code is not displayed. after the space is initialized several times and the device is reinstalled, it is preliminarily determined that there are bom files in the website program file. the common one is UTF-8, which is UTF-8 + bom, so problems have emerged. But now you don't know which file is actually? What should I do?
This method will work in the future!

First, create a local file named RemoveBom. php.
Next, copy and paste the following code into the file named above, save it, upload it to the root directory of the website, and then run the file directly!
The RemoveBom. php code is as follows:

 ";} Else {$ dirname = $ basedir. "/". $ file; checkdir ($ dirname) ;}} closedir ($ dh) ;}} function checkBOM ($ filename) {global $ auto; $ contents = file_get_contents ($ filename ); $ charset [1] = substr ($ contents, 0, 1); $ charset [2] = substr ($ contents, 1, 1 ); $ charset [3] = substr ($ contents, 2, 1); if (ord ($ charset [1]) = 239 & ord ($ charset [2]) = 187 & ord ($ charset [3]) = 191) {if ($ auto = 1) {$ rest = Substr ($ contents, 3); rewrite ($ filename, $ rest); return ("BOM found, automatically removed. _ http://host.fbi1.net ");} else {return (" BOM found. ") ;}} else return (" BOM Not Found. ");} function rewrite ($ filename, $ data) {$ filenum = fopen ($ filename," w "); flock ($ filenum, LOCK_EX); fwrite ($ filenum, $ data); fclose ($ filenum) ;}?>

The above code is used to remove BOM! The actual effect is exceptionally good. this problem can be solved in minutes.
