combining multiple htaccess rules - php

Question

i have a htaccess rule that remove .php extension:
`RewriteEngine On
ErrorDocument 403 "Page not exist"
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/$ $1.php
RewriteRule ^([^/]+)/([^/]+)/$ /$1/$2.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule (.*)$ /$1/ [R=301,L]`
the htaccess rule below redirects to stream.php file:
`RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /core/musicbox/stream/?tag=$1 [NC,L,QSA]`
Both rule works individually, but when combined,the rule placed below does not work.

Answer 1

You have the same conditions twice:
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
Which means:
!-f: File %{REQUEST_FILENAME} doesn't exist.
!-d: Directory %{REQUEST_FILENAME} doesn't exist.
If both are true and the next one (in the first set of rules) is also true:
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
Then the next rule will do a 301 redirect (R=301) and stop processing rules (L).
RewriteRule (.*)$ /$1/ [R=301,L]
Actually, maybe there's a missing ^ in there. It should be:
RewriteRule ^(.*)$ /$1/ [R=301,L]
Anyway, that means that the second set of conditions and the subsequent rule won't be reached:
RewriteRule ^(.*)$ /core/musicbox/stream/?tag=$1 [NC,L,QSA]
Probably you don't need those first R=301 and L flag. I think this is how it should look like:
RewriteEngine On
ErrorDocument 403 "Page not exist"
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^([^/]+)/$ $1.php
RewriteRule ^([^/]+)/([^/]+)/$ /$1/$2.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule ^(.*)$ /$1/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /core/musicbox/stream/?tag=$1 [NC,L,QSA]
