导读:下面小编就为大家带来一篇php解析mht文件转换成html的实例。小编觉得挺不错的,现在就分享给大家,也给大家做个参考。一起跟随小编过来看看吧

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。

/**

  • 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();

}
return null;

}
