php解析mht文件转换成html的实例-php教程

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。

<?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, '.mht', 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;
}
