php解析mht文件，使用編輯器打開可以看到base64編碼所以，mht是可以轉換成html的。

<?php

/**
 * 針對Mht格式的文件進行解析
* 使用例子:
* 
* function mhtmlParseBody($filename) {

	if (file_exists ( $filename )) {

		$filename = strtolower ( $filename );
		if (strpos ( $filename, '.mht', 1 ) == FALSE) return false;
			
		
		$o_mhtml = new mhtml ();
		$o_mhtml->set_file ( $filename );
		$o_mhtml->extract ();
