Hiding PHP file extension

Do you want to hide your web site’s server script identity ? If you don’t want to reveal the programming language ( server side script ) of your website to visitors of website so that any hacker or spammer will not be able to intrude or inject any code in your website.

Here is a small technique for you, you can use .html or .asp file to work as a php file i.e. use .asp or .html extension instead of .php. You just need to create a .htaccess file and put the following code in the .htaccess file. Remember that the .htaccess file should be placed in the root folder of your website.

# Make PHP code look like asp or perl code
AddType application/x-httpd-php .asp .pl

if you place the the above code in the .htaccess file then you can use contact.asp as the name of the file. Now a visitor thought that it is a ASP file but this file contains the codes of PHP.

You can put the following code in .htaccess file to work .htm or .html file as PHP file.

# Make all PHP code look like HTML
AddType application/x-httpd-php .htm .html

    Thanks for sharing this technique. I kinda feel like a traitor for not standing up and defending PHP and open source constantly, but yes, there are some business people that still think traditional open source web sites (.php, perl, python), are somehow inferior to .aspx, .cfm and even .jsp sites. (I’m not talking here about [overtly] deceiving the client, or telling them they have a ASP.NET site when its a PHP site. However, if one of these (IMHO) “stuck up”, opinionated, and money wasting customers want to believe that a site is .aspx (when it’s really .php), then he has really deceived himself.

    Thanks for sharing this technique. I’ll try not to abuse it. :)

  2. nice trick, I heard about this a while ago…but I like your presentation (simple)

    “If you don’t want to reveal the programming language ( server side script ) of your website to visitors of website so that any hacker or spammer will not be able to intrude or inject any code in your website.”

    Obscurity is *not* a security measure; just making it not immediately obvious what language you’re coding in server-side doesn’t prevent any sort of code injection. Code injection is prevented by cleaning user input before passing it to functions like eval() whch can execute arbitrary code.

    A nice technique worth sharing – but IMHO rather than making one extension behave like another it’s better to use mod_rewrite or an equivalent. Then you can have e.g. http://www.example.com/show_users map to file /show_users.php

  4. I think it looks a lot cleaner to come up with a nice mod rewrite system that completely removes file extensions and interprets the query string. looks a lot neater.

  5. Rob and Jasper i agree with you that with mod_rewrite you can do it in a better way and if your good in regular expression then that is the best way, but it’s a bit tedious for the beginners to write the regular expression in .htaccess.

    You may be hiding the extension, but you’re still sending out “X-Powered-By: PHP/4.4.6” in the headers.

    😉

  7. I had problems getting “AddType” to work on a netnation hosted site. Turns out using “AddHandler” did the trick: http://fishdujour.typepad.com/blog/2007/08/htaccess-settin.html

  8. Leslie Hoare

    A better way is to show no extension at all, you can do that with this line:

    Options +MultiViews

    That’ll make any file type (like .html, .jpg, etc) visible without a file extension too. And it’ll make it easier if you decide later on to switch scripting languages, say to Ruby or Java :)

  9. yes Leslie you can hide the extension with Options +MultiViews but you cannot the change its extension like .asp or .html with that.

  10. will

    in response to Aidan Samuel:
    you can change the X-Powered-By with a couple tweaks to your php.ini and apache configurations.

    the best use (in my opinion of hiding php), is to make a director where i will generate CSS or Javascript, and have an .htaccess with: “AddType application/x-httpd-php .css” in it. it can also be used to generate graphs or captchta images. i can then transparently generate javascript or css on-the-fly.

    How to hide the script of GET. like index.php?id=share

  18. well you can user POST or SESSION variable if you want to hide the GET variables and even you can use apache’s mod_rewrite module for rewriting the url.So there are lots of option according to your need

  19. Hi,

    I have written a script that basicly creates an image for use in forum signatures, which dynamically updates with stats from database every time it is called, the image works fine and everything, my problem is that the image has an extension of .php and some forums will only allow .jpg or .gif as a file extension in signatures, is there any way I can get apache and php to read just this one file as a php script if I change it to .jpg extension, I have tried the method above using .htaccess, it doesn’t seem to work.

    hi,
    i used your code but this is not working in my ssh server.could you tell me the best option so that i can see my php page like asp or pearl or html.
    thank

  21. Is .htaccess overriding is allowed in your server.I think .htaccess is not making effect please consult with your server administrator , I don’t think there is problem in the code

  22. Thanks….:)

  23. Please don’t do it this way 😛

    Under Apache 2 just enable:
    Options +MultiViews

    And then in your code use –
    htto://domain.tld/some_uri

    On the server some_uri will evaluate to some_uri.html, some_uri.cgi, some_uri.pl, or some_uri.php — however this appraoch forces web designers to be much more accurate their web resource declarations and layouts because you can only have some_uri evaluate to 1 thing otherwise the server displays mutiple matches which can lead to a security leak … maybe enforcing good web design skills is a good thing long term.

  25. thanks! nice mod, nice presentation.

    we have a client that is migrating ecommerce systems – their current ecommerce system is heavily indexed in the search engines with landing pages containg the asp extension. the newly designed and developed site will have php extensions, so to keep those pages’ performance up, we’ll rewrite the php extension to asp.

    I’m goign to sound like an idiot, but is .htaccess the name of the file or the file extension?

  27. well it seems that you are not familiar with the file system of the linux and unix so you’re asking this question. .htaccess is the name of the file dude…

    hi,thanks
    this way is good, but I wan`t change my PHP files extension(about 100 files and link).
    how can I use this code without change file extension to Html

    thanks

  30. Bob

    Please; don’t abuse AddType – which sets MIME types – to invoke handlers. This is wrong since 1997 and was a dirty hack those days. You want to invoke a handler, so AddHandler is the directive to use.
