Mod rewrite - hiding php extensions

Discussion in 'Apache' started by ollyno1uk, Dec 22, 2008.

    Hi there

    I have a site with a load of php extensions that I would like to make .html.
    SEMrush
    I have looked for a solution online and found this :

    
    RewriteBase /
    RewriteRule ^(.*)\.php $1.html [R=301,L]
    RewriteRule ^(.*)\.html $1.php [L]
    
    Code (markup):
    However this results in a redirect loop.

    Is there a simple way I can rewrite the .php to .html extensions and 301 the old to the new?

    Thanks

    thanks for this.

    I now get an error to say that the html file is not found.

    Ah sorry, I misunderstood what you wanted to do last time.

    I think this might do the trick.

    RewriteEngine On 
    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^(.*)\.php$ /$1.html [R=301,L]
    RewriteRule ^(.*)\.html$ /$1.php [L]
    Code (markup):

    You are a genius - this is perfect.

    Can I ask what the ENV:REDIRECT_STATUS actually does so I can understand it?

    The problem before was when you requested say test.html, Apache would process the .htaccess file and make a sub request for test.php. At this point .htaccess is processed again, and because test.php matches the rewrite rule, it's redirected to test.html, and the loop will start again!

    REDIRECT_STATUS is a server variable. If a sub request is made, this is the HTTP response status code of the original request, otherwise it'll be empty. Therefore you can test against this to avoid a loop.

    This condition is checking that REDIRECT_STATUS is empty:
    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    Code (markup):
    I hope this helps somewhat.
