Rewrite php application to get seo welcome url

I have a php application that needs to be partially rewritten due to a client request for SEO searches.

My links are as follows:

www.mysite.com/articles_en.php?artid=89 where I will need to change the url:

www.mysite.com/articleTitle

Then I have this url:

www.mysite.com/halls.php?fairid=65, which should become

www.mysite.com/fairname

And www.mysite.com/companies.php?fairid=65&hallid=23, which should become

www.mysite.com/fairname/hallname

You get the idea.

I need help with this approach. Is it a good idea in tables of fairs, halls, and articles to create a field in a table with a name, such as an alias, and then try to rewrite the URL? Can someone help me with the steps, how to create this script, or point me to a better approach?

I am well versed in php, but not very good with regular expressions, so I will be lost in the .htaccess part.

Any help would be greatly appreciated.

Regards, Zoran

.htaccess something like:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^?]*) /url_rewrite.php?path=$1 [L,QSA]

database table:

+------+--------+
| path | url    |
+------+--------+

With the path as the PRIMARY KEY.

And a PHP script called url_rewrite.phpthat takes a path parameter from a URL, searches the database to find the real URL and does an HTTP 301 redirect.

url_rewite.php ( - mysql_query()) - PDO MySQLi 't , ).

<?php
// -- database connection and any intialisation stuff you may have might go here ...

//get the path
$sPath = !empty($_GET['path']);

// -> error trapping for empty paths here

//retrieve the "real" url from the database
$dbQry = mysql_query("SELECT `url` FROM `seourls` WHERE `path` = '" . mysql_real_escape_string($sPath) . "' LIMIT 0, 1");

// -> error trapping here for query errors here

$dbResponse = mysql_fetch_row($dbQuery);

// -> error trapping here for empty recordsets here

$sRealPath = $dbResponse[0]; # which might be "/articles_en.php?artid=89"

//redirect
header("HTTP/1.1 302 Found");
header("Status: 302 Found"); # for Chrome/FastCGI implementation
header("Location: {$sRealPath}");
die();

?>
