No more nonsense, just go to the code
"; } closedir($dh); } function checkBOM ($filename) { $contents=file_get_contents($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) { $rest=substr($contents, 3); rewrite ($filename, $rest); return true; } else return ("BOM Not Found."); } function rewrite ($filename, $data) { $filenum=fopen($filename,"w"); flock($filenum,LOCK_EX); fwrite($filenum,$data); fclose($filenum); } ?>
