Question

I have this rewrite rule in my .htaccess

RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^([^/.]+)/?(.*)$ /$1.php/$2 [QSA,L]
RewriteRule ^api/([a-z]+)/([a-z]+) /api/$1_$2.php

How can I modify this to change everything in my URL to lowercase?

i.e. This:

www.mysite.com/ThisURL/SHOULD/be_all_lowercse

Should be

www.mysite.com/thisurl/should/be_all_lowercase

Answer 1

Define a RewriteMap of type int (internal) referencing the tolower function, and call it where you want to do the lowercasing:

RewriteMap  lc int:tolower
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^([^/.]+)/?(.*)$ /${lc:$1}.php/${lc:$2} [QSA,L]
RewriteRule ^api/([a-z]+)/([a-z]+) /api/${lc:$1}_${lc:$2}.php}
