.htaccess for clean URL not working

Question

I am working with PHP and htacess for the first time. I am passing a variables in a query string to a URL and want this URL to look clean. Please help.
.htaccess file

RewriteEngine On
RewriteRule ^id-([0-9]+)/([0-9A-Za-z]+).html  /detail.php?id=$1&display=$2

PHP code passing from one file to detail page URL is:

<a href='/detail.php?id={$info[id]}&display=$title1'>

Please help.

Answer 1

You need to print out the new URL in order to get it rewritten by mod_rewrite. Because mod_rewrite can only rewrite URLs that are requested. So try this:

<a href='/id-{$info[id]}-$title1.html'>
