批量清除php文件中bom的方法

2. //此文件用于快速测试UTF8编码的文件是不是加了BOM，并可自动移除
3. $basedir="."; //修改此行为需要检测的目录，点表示当前目录
4. $auto=1; //是否自动移除发现的BOM信息。1为是，0为否。
5. //link: http://bbs.it-home.org
6. //以下不用改动
7. if ($dh = opendir($basedir)) {
8. while (($file = readdir($dh)) !== false) {
9. if ($file!='.' && $file!='..' && !is_dir($basedir."/".$file))
10. echo "filename: $file ".checkBOM("$basedir/$file")."
    ";
11. }
12. closedir($dh);
13. }
14. function checkBOM ($filename) {
15. global $auto;
16. $contents=file_get_contents($filename);
17. $charset[1]=substr($contents, 0, 1);
18. $charset[2]=substr($contents, 1, 1);
19. $charset[3]=substr($contents, 2, 1);
20. if (ord($charset[1])==239 && ord($charset[2])==187 && ord($charset[3])==191) {
21. if ($auto==1) {
22. $rest=substr($contents, 3);
23. rewrite ($filename, $rest);
24. return ("BOM found, automatically removed.");
25. } else {
26. return ("BOM found.");
27. }
28. }else
29. return ("BOM Not Found.");
30. }
31. function rewrite ($filename, $data) {
32. $filenum=fopen($filename,"w");
33. flock($filenum,LOCK_EX);
34. fwrite($filenum,$data);
35. fclose($filenum);
36. }
37. ?>

2、批量去除PHP文件中bom的代码

2. if (isset($_GET['dir'])){ //设置文件目录
3. $basedir=$_GET['dir'];
4. }else{
5. $basedir = '.';
6. }
7. $auto = 1;
8. checkdir($basedir);
9. function checkdir($basedir){
10. if ($dh = opendir($basedir)) {
11. while (($file = readdir($dh)) !== false) {
12. if ($file != '.' && $file != '..'){
13. if (!is_dir($basedir."/".$file)) {
14. echo "filename: $basedir/$file ".checkBOM("$basedir/$file")."
    ";
15. }else{
16. $dirname = $basedir."/".$file;
17. checkdir($dirname);
18. }
19. }
20. }
21. closedir($dh);
22. }
23. }
24. function checkBOM ($filename) {
25. global $auto;
26. $contents = file_get_contents($filename);
27. $charset[1] = substr($contents, 0, 1);
28. $charset[2] = substr($contents, 1, 1);
29. $charset[3] = substr($contents, 2, 1);
30. if (ord($charset[1]) == 239 && ord($charset[2]) == 187 && ord($charset[3]) == 191) {
31. if ($auto == 1) {
32. $rest = substr($contents, 3);
33. rewrite ($filename, $rest);
34. return ("BOM found, automatically removed._http://bbs.it-home.org");
35. } else {
36. return ("BOM found.");
37. }
38. }
39. else return ("BOM Not Found.");
40. }
41. function rewrite ($filename, $data) {
42. $filenum = fopen($filename, "w");
43. flock($filenum, LOCK_EX);
44. fwrite($filenum, $data);
45. fclose($filenum);
46. }
47. ?>
