I wrote a local name/phone/address search engine for my city.
Users must be able to quick-access the results by going to either of these urls:
RewriteRule ^([A-Za-z-\s]+)/([A-Za-z-\s]+)$ /index.php?lastname=$1&name=$2 [QSA,L]
The \s will take care of blank spaces.
Can you try this? ([a-z-\s]+)
RewriteRule ^([0-9]+)$ /html/index.php?phone=$1 [QSA,L]
RewriteRule ^([A-Za-z-\s]+)$ /html/index.php?lastname=$1 [QSA,L]
RewriteRule ^([A-Za-z-\s]+)/([A-Za-z-\s]+)$ /html/index.php?lastname=$1&name=$2 [QSA,L]
