Not really the job for PHP, look into mod_rewrite or similar (depending on what http server you're running on).Reese Moore– Reese Moore2010-12-24 08:10:10 +00:00Commented Dec 24, 2010 at 8:10

@HeLp what do you mean by 'turn into'? If you want to cause a redirect, yes you need to use htaccess if you need to rewrite data that you are turning into links then yes, you could do it in PHP with a regex, please clarify exactly what you want to do.tobyodavies– tobyodavies2010-12-24 08:16:21 +00:00Commented Dec 24, 2010 at 8:16

What do you want to do with these urls? serve URL1 as if it were URL2, display them to people, bake them a cake? We need more details to answer the question.tobyodavies– tobyodavies2010-12-24 08:21:57 +00:00Commented Dec 24, 2010 at 8:21

As has been suggested, this is something to be done through HTACCESS and mod_rewrite rules. The best trick for things like this would be to have a go, share what you have managed to come up with (and the results or bugs) and people will then help you find a complete solution.
That being said, I would suggest something like the following, in a file called ".htaccess" in your webroot.
Options +FollowSymLinks
RewriteEngine On
RewriteCond %{REQUEST_URI} !-f # Means if the requested address is not a file
RewriteCond %{REQUEST_URI} !-d # Means if the requested address is not a dir
RewriteRule ^([^/]+)/([^/]+)/([^/]+)$ index.php?cat=$1&sub1=$2&sub2=$3
I have not tested the above code, but it would be where I would start, and maybe mix with some independent research as required...

That's just simple string manipulation - but note that changing the request URI within* your script won't automatically populate the relevant $_GET variables.
To change the string:
<?php
$input_url='http://www.example.com/categories/fruit/apple/green';
$parts=parse_url($input_url);
$embeds=explode('/',$parts['path']);
$new_path=array_shift(embeds) . '/index.php'; // store 'categories' for later
$count=1;
$join=strlen($parts['qry']) ? '&' : '?';
foreach ($embeds as $val) {
$parts['query'].=$join . 'ub' . $count . '=' . urlencode($val);
$join='&';
}
$out_url=$parts['scheme'] . '://'
. ($parts['username'] . $parts['password']) ?
$parts['username'] . ':' $parts['password'] . '@' : ''
. $parts['host'] . '/' . $new_path
. $parts['query']
. '#' . $parts['fragment'];
print $out_url;
