"/". $ 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. _ csdn.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) ;}?> Appendix. bom header information description. In a UTF-8 encoded file, BOM occupies three bytes in the file header to indicate that the file belongs to UTF-8 encoding. PHP cannot recognize the bom header. if you use notepad to edit UTF-8 encoding, an error occurs. Remove the bom header. 1. after the editplus method editor goes to the BOM header and is changed to the UTF8 encoding format, a hidden string (that is, BOM) appears before the saved file ), used by the editor to identify whether the file is UTF-8 encoded.
