Transaction in Zend Framework

http://framework.zend.com/manual/en/zend.db.html#zend.db.adapter.transactions

The MyISAM engine doesn't support transaction.
You may need to use InnoDB instead.
Read the following post for my question:
http://stackoverflow.com/questions/1083857/cannot-rollback-transaction-in-zend-framework

setting of htaccess

1. php_flag register_globals off
instead of just by $abcif this flag sets to off, program will be only able to get the $_GET["abc"], $_POST["abc"],etc if the url is url.html?abc=123

2. php_flag magic_quotes_gpc off
This flag is used to originally give backslash to gpc(get, post, cookie) to prevent SQL injection.

3. php_flag short_open_tag on
Allow the use of short open tag < ? instead of < ?php

4. Options -Indexes
Disallow directory browsing

5. DirectoryIndex index.php index.htm index.html
If the user types the directory name, we search through the list of index.php to show it.
