记得运行代码前先把文件备份一下哦,避免出现失败问题。

代码一:

  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 ("<font color=red>BOM found, automatically removed.</font>");
      } else {
        return ("<font color=red>BOM found.</font>");
      }
    }
    else return ("BOM Not Found.");
  }

代码二:

<"htmlcode">
##把该文件放在需求去除BOM头的目录下跑一下却可。
<"/" . $file )) { // 如果是文件
          echo "filename: $basedir/$file " . checkBOM ( "$basedir/$file" ) . " <br>";
        } else {
          $dirname = $basedir . "/" . $file; // 如果是目录
          checkdir ( $dirname ); // 递归
        }
      }
    }
    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 ( $charset [3] ) == 191) { // BOM
                                                   // 的前三个字符的ASCII
                                                   // 码分别为
                                                   // 239
                                                   // 187
                                                   // 191
    if ($auto == 1) {
      $rest = substr ( $contents, 3 );
      rewrite ( $filename, $rest );
      return ("<font color=red>BOM found, automatically removed.</font>");
    } else {
      return ("<font color=red>BOM found.</font>");
    }
  } else
    return ("BOM Not Found.");
}
function rewrite($filename, $data) {
  $filenum = fopen ( $filename, "w" );
  flock ( $filenum, LOCK_EX );
  fwrite ( $filenum, $data );
  fclose ( $filenum );
}
