how to escape "/" from mod_rewrite - apache

Question

this is my .htaccess file thnx to #Gyrocode-com
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^p/(.*)$ fun.php?p=$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^u/(.*)$ user.php?u=$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^u/([^/]+)/([1-9]+)$ user.php?c=$1&p=$2 [L] #my problem is here
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([1-9]+)$ index.php?p=$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/([^/]+)$ index.php?c=$1&p=$2 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/$ index.php?c=$1 [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)$ /jokes/$1/ [R]
everything works great except whene i try to go to this link
localhost/u/user1/2
which suppose to take me to page number 2 of user1
but instead it catches user1/2 as the value of variable (u)
and what I want is u=user1 ; p= 2;

Your rules can be refactored to this:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^p/([^/]+)/?$ fun.php?p=$1 [L]
RewriteRule ^u/([^/]+)/?$ user.php?u=$1 [L]
RewriteRule ^u/([^/]+)/([1-9]+)$ user.php?c=$1&p=$2 [L]
RewriteRule ^([1-9]+)$ index.php?p=$1 [L]
RewriteRule ^([^/]+)/([^/]+)$ index.php?c=$1&p=$2 [L]
RewriteRule ^([^/]+)/$ index.php?c=$1 [L]
RewriteRule ^([^/]+)$ /jokes/$1/ [R,L]
Using ([^/]+) instead of (.*) to restrict matching to anything before /
Instead of using RewriteCond %{REQUEST_FILENAME} -f and RewriteCond %{REQUEST_FILENAME} -d before each rule it is better to use that in a separate rule as shown.
