Create url for mod_rewrite
Creating urls with Search engine optimized keywords from database records involves more than just mod_rewrite and htaccess synchronization. The first step of a good search engine indexing strategy is to take one of your database fields as index (title is a good one) , transform it by removing spaces, special characters, and if necessary append record unique identifier to the generated string. Here is a sample function that transforms a string to make it file compliant using a regular expression to discard non alphanumeric characters and replace spaces with dashes :
function make_url($string){
$pattern = “([^[[:alnum:]|[:space:]|[:blank:]])+”;
$anchor = ereg_replace($pattern, ”, strtolower($string));
$pattern = “([[:space:]]|[[:blank:]])+”;
$anchor = ereg_replace($pattern, ‘-’, $anchor);
return short_name($anchor); // return the short filtered name
} # end function
