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();
- }
