only top condition is working not others for url rewriting?

问题

This is my htaccess code for url-rewriting. I have a problem here.

Options +FollowSymLinks -MultiViews -Indexes

<IfModule mod_rewrite.c>

DirectoryIndex index.php

RewriteEngine on 

RewriteCond %{REQUEST_FILENAME} !-d 
RewriteCond %{REQUEST_FILENAME}\.php -f 
RewriteRule ^(.*)$ $1.php

ErrorDocument 404 404error.php

RewriteEngine On

RewriteRule ^([A-Za-z0-9-]+)?$ specification.php?url=$1

RewriteRule ^([A-Za-z0-9-]+)?$ news.php?url=$1

RewriteRule ^([A-Za-z0-9-]+)?$ social.php?url=$1

</IfModule>

here are three pages with different data. When I click for spcification.php page data then it will redirect me on same page but if my this code is above from this then it will redirect me to on news.php.

RewriteRule ^([A-Za-z0-9-]+)?$ news.php?url=$1

only top condition work not others.

From what I know you cannot use same rule for multiple conditions like this

RewriteRule ^([A-Za-z0-9-]+)?$ specification.php?url=$1

When first rule matched it stop searching for same condition, instead you have to use

RewriteRule ^specification/([A-Za-z0-9-]+)?$ specification.php?url=$1 [L]
RewriteRule ^news/([A-Za-z0-9-]+)?$ news.php?url=$1 [L]

Your original url will look like this domain.com/news/value.
