.htaccess 5个变量的问题

Question

Following is my .htaccess file.

AddDefaultCharset utf-8
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} -f
RewriteRule .* - [L]

DirectoryIndex index.php
RewriteRule ^([a-zA-Z0-9_-]{3,20})/([^/]+)/([^/]+)?$ index\.php?page=$1&s=$2&o=$3&p=$4&q=$5 [L]

RewriteRule ^([a-zA-Z0-9_-]{3,20})/([^/]+)/([^/]+)?$ index\.php?page=$1&s=$2&o=$3&p=$4 [L]

RewriteRule ^([a-zA-Z0-9_-]{3,20})/([^/]+)/([^/]+)?$ index\.php?page=$1&s=$2&o=$3 [L]

RewriteRule ^([a-zA-Z0-9_-]{3,20})/([^/]+)?$ index\.php?page=$1&s=$2 [L]

RewriteRule ^([a-zA-Z0-9_-]{3,20})/?$ index\.php?page=$1 [L]

RewriteRule ^([a-zA-Z0-9_-]{3,20})?$ index\.php?page=$1 [L]

ErrorDocument 404 /404

when i do

ehco "<pre>";
print_r($_REQUEST);
echo "</pre>";

with 3 parameters, it shows me

Array
(
    [page] => test
    [s] => 1
    [o] => 9
    [p] => 
    [q] => 
)

but if more than 3 parameters, it says not found. The .htaccess is working fine for the following URL myhost/mysite/page/s/o but not for myhost/page/s/o/p

some changes of your code:

AddDefaultCharset utf-8
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} -f
RewriteRule .* - [L]

DirectoryIndex index.php
RewriteRule ^([a-zA-Z0-9_-]{3,20})/([^/]+)/([^/]+)/([^/]+)/([^/]+)?$ index\.php?page=$1&s=$2&o=$3&p=$4&q=$5 [L]

RewriteRule ^([a-zA-Z0-9_-]{3,20})/([^/]+)/([^/]+)/([^/]+)?$ index\.php?page=$1&s=$2&o=$3&p=$4 [L]

RewriteRule ^([a-zA-Z0-9_-]{3,20})/([^/]+)/([^/]+)?$ index\.php?page=$1&s=$2&o=$3 [L]

RewriteRule ^([a-zA-Z0-9_-]{3,20})/([^/]+)?$ index\.php?page=$1&s=$2 [L]

RewriteRule ^([a-zA-Z0-9_-]{3,20})/?$ index\.php?page=$1 [L]

RewriteRule ^([a-zA-Z0-9_-]{3,20})?$ index\.php?page=$1 [L]
