I have made a website of online shopping in php...should i migrate it to asp .net or php itself is a good platform ?
PHP is better that asp .net unless you have a specific reason or issue using it... You can read the debate here :- http://www.bizfive.com/articles/web-design/comparing-php-and-asp.net/
you may migrate beacause coding in php is somewhat less secured than php and as per it is the online shoppng site it needs some security
I disagree you on that.... In fact the security topic does not depend on a specific language it depends on the coder... If the coder left some holes in the PHP code he is likely to repeat that in the .asp .net code... If you feel PHP is less secured provide a reason for it!!!
I thought you wrote PHP less secured than asp .net BTW :- I still think you meant that only because PHP less secured than PHP means nothing.... I think its a typo shabbir...
It can be other way round as well and so you never know. BTW Facebook is on PHP platform and if you still think it is less secured than any other language on internet, it is time to upgrade you kb
