htaccess,mod rewrite tips

if your intention to code and decode mod_rewrite urls and handle it with php and mysql ,this should work

to convert to url
$url = preg_replace('/[^A-Za-z0-9_-]+/', '-', $string);


And to check in mysql with the url value,use the same expression discounting '-'.first replace the url value  with php using preg_replace  and use with mysql REGEXP

$sql = "select * from table where fieldname_to_check REGEXP '".preg_replace("/-+/",'[^A-Za-z0-9_]+',$url)."'"
