title: Remove php extension from URL - except one and only one URL using htaccess
body: <p>I'm using this code to remove the .php from the end of my URL's making them more SEF.</p>
  
  <pre><code>RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s/(.+)\.php[^\s]* [NC]
  RewriteRule ^ /%1 [R=301,NE,L]
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME}.php -f
  RewriteRule ^ %{REQUEST_URI}.php [QSA,NC,L]
  </code></pre>
  
  <p>This is generic and works perfectly for every UR but I would like to know how to create <strong>an exception for one and only one URL</strong>, ie: 
  <code>http://www.domain.com/services</code> to <code>http://www.domain.com/services.php</code>
  without influencing all the others. Is this possible?</p>
  
  <p>I've tried a simples Redirect but entered a loop.</p>
  
  <h1>! EDITED !</h1>
  
  <p>I failed to mention I have also these rules:</p>
  
  <p><strong>Add www.</strong></p>
  
  <pre><code>RewriteCond %{HTTP_HOST} !^www\.
  RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
  </code></pre>
  
  <p><strong>Remove index</strong> (the extension .php from index has been trimmed already)</p>
  
  <pre><code>RewriteCond %{THE_REQUEST} ^[A-Z]{3,}\s(.*)/index/?([^\ \?]*) [NC]
  RewriteRule ^ %1/%2 [R=301,L]
  </code></pre>
