php解析mht文件转换成html的实例

PHP解析mht文件，使用编辑器打开可以看到base64编码所以，mht是可以转换成html的。

rush:PHP;"> /**

针对Mht格式的文件进行解析
使用例子:

function mhtmlParseBody($filename) {

if (file_exists ( $filename )) {
if (is_dir ( $filename )) return false;

  $filename = strtolower ( $filename );
  if (strpos ( $filename,'.mht',1 ) == FALSE) return false;

  $o_mhtml = new mhtml ();
  $o_mhtml->set_file ( $filename );
  $o_mhtml->extract ();
  return $o_mhtml->get_part_to_file(0);

}
return null;
}

function mhtmlParseAll($filename) {

if (file_exists ( $filename )) {
    if (is_dir ( $filename )) return false;

    $filename = strtolower ( $filename );
    if (strpos ( $filename,1 ) == FALSE) return false;


    $o_mhtml = new mhtml ();
    $o_mhtml->set_file ( $filename );
    $o_mhtml->extract ();
    return $o_mhtml->get_all_part_file();
