Redirect all to index php using htaccess

Question

I am writing a simple PHP-based MVC-ish framework  I want this framework to be able to be installed in any directory  My PHP script grabs the request uri and breaks it off into segments  It makes segment 1 the controller and segment 2 the action  This goes all fine  when I do this  http   www example com mvc module test   It will go to the specific module controller and method  Now I have a default controller   the home controller  which is in folder home  Now when I access this folder directly  http   www example com mvc home  It will display a 403 forbidden   because this folder does exist  instead it should also go back to  http   www example com mvc index php If I would have installed the framework in a different folder  lets say folder framework it has to redirect back to http   www example com framework index php I would like to redirect every folder and php file back to the index php  leaving everything else the way it is  My first problem I encountered was it never redirects to the right folder  always to the domain root folder  This is what I tried   RewriteEngine on RewriteCond   REQUEST FILENAME   -d RewriteCond   REQUEST FILENAME   -f RewriteRule   index php  L

Silly answer but if you can t figure out why its not redirecting check that the following is enabled for the web folder     AllowOverride All  This will enable you to run htaccess which must be running   there are alternatives but not on will cause problems https   httpd apache org docs 2 4 mod core html allowoverride

just in case you were still wondering how to redirect all request either if the directory exists  for core framework folders and files  to the framework index handler  after some error success attempts just noticed I just needed to change the RewriteCond in the  htaccess file  RewriteCond   REQUEST FILENAME   -f RewriteCond   REQUEST FILENAME   -d   the above condition states  not found files  and  not found directories   ok  what if just remove  not found    -d  line  and ended with something like the below   RewriteEngine on RewriteBase  framework  RewriteCond   REQUEST FILENAME   -f RewriteRule         framework index php  L QSA    It worked for me like a charm

There is one  trick  for this problem that fits all scenarios  a so obvious solution that you will have to try it to believe it actually works        Here it is       lt IfModule mod rewrite c gt      RewriteEngine On     RewriteCond   REQUEST FILENAME   -f  OR     RewriteCond   REQUEST FILENAME   -f    RewriteRule        index php  L QSA    lt  IfModule gt    Basically  you are asking MOD REWRITE to forward to index php the URI request always when a file exists AND always when the requested file doesn t exist   When investigating the source code of MOD-REWRITE to understand how it works I realized that all its checks always happen after the verification if the referenced file exists or not  Only then the RegEx are processed  Even when your URI points to a folder  Apache will enforce the check for the index files listed in its configuration file   Based on that simple discovery  turned obvious a simple file validation would be enough for all possible calls  as far as we double-tap the file presence check and route both results to the same end-point  covering 100  of the possibilities   IMPORTANT  Notice there is no     in index php  By default  MOD REWRITE will use the folder it is set as  base folder  for the forwarding  The beauty of it is that it doesn t necessarily need to be the  root folder  of the site  allowing this solution work for localhost  and or any subfolder you apply it   Ultimately  some other solutions I tested before  the ones that appeared to be working fine  broke the PHP ability to  require  a file via its relative path  which is a bummer  Be careful   Some people may say this is an inelegant solution  It may be  actually  but as far as tests  in several scenarios  several servers  several different Apache versions  etc   this solution worked 100  on all cases

You can use something like this   RewriteEngine on RewriteRule       index php  L    This will redirect every query to the root directory s index php  Note that it will also redirect queries for files that exist  such as images  javascript files or style sheets

To redirect everything that doesnt exist  to index php   you can also use the FallBackResource directive   FallbackResource  index php   It works same as the ErrorDocument   when you request a non-existent path or file on the server  the directive silently forwords the request  to index php    If you want to redirect everything  including existant files or folders   to index php   you can use something like the following    RewriteEngine on  RewriteRule      index  php       index php  L    Note the pattern      index  php       matches any uri except index php we have excluded the destination path to prevent infinite looping error

Your rewrite rule looks almost ok   First make sure that your  htaccess file is in your document root  the same place as index php  or it ll only affect the sub-folder it s in  and any sub-folders within that - recursively    Next make a slight change to your rule so it looks something like   RewriteEngine on RewriteCond   REQUEST FILENAME   -f RewriteCond   REQUEST FILENAME   -d RewriteRule         index php path  1  NC L QSA    At the moment you re just matching on   which is one instance of any character  you need at least    to match any number of instances of any character   The   GET  path   variable will contain the fake directory structure  so  mvc module test for instance  which you can then use in index php to determine the Controller and actions you want to perform    If you want the whole shebang installed in a sub-directory  such as  mvc  or  framework  the least complicated way to do it is to change the rewrite rule slightly to take that into account   RewriteRule         mvc index php path  1  NC L QSA    And ensure that your index php is in that folder whilst the  htaccess file is in the document root    Alternative to   GET  path    updated Feb  18 and Jan  19   It s not actually necessary  nor even common now  to set the path as a   GET variable  many frameworks will rely on   SERVER  REQUEST URI   to retrieve the same information - normally to determine which Controller to use - but the principle is exactly the same   This does simplify the RewriteRule slightly as you don t need to create the path parameter  which means the OP s original RewriteRule will now work    RewriteEngine on RewriteCond   REQUEST FILENAME   -f RewriteCond   REQUEST FILENAME   -d RewriteRule       index php  L QSA    However  the rule about installing in a sub-directory still applies  e g   RewriteRule       mvc index php  L QSA        The flags   NC   No Case  not case sensitive  not really necessary since there are no characters in the pattern   L   Last  it ll stop rewriting at after this Rewrite so make sure it s the last thing in your list of rewrites   QSA   Query String Append  just in case you ve got something like  like penguins on the end which you want to keep and pass to index php

I just had to face the same kind of issue with my Laravel 7 project  in Debian 10 shared hosting  I have to add RewriteBase   to my  htaccess within  public  directory  So the  htaccess looks a like RewriteEngine On RewriteBase   RewriteCond   REQUEST FILENAME   -f RewriteCond   REQUEST FILENAME   -d RewriteRule       index php  L QSA
