Want to change a url

[james438]

The following does the same thing as the code I posted earlier, but has been simplified somewhat.

<?php
$test="http://www.mytravelsite.com/states/cities/thiscity/0/apage.shtml";
preg_match('/\/{1}[^\/]*?\/{1}(?!.*?\/).*/',$test, $extract);
echo "http://www.inchicago.com$extract[0]";
?>

EDIT: and simplified a little further:

<?php
$test="http://www.mytravelsite.com/states/cities/thiscity/0/apage.shtml";
preg_match('/\/[^\/]*?\/(?!.*?\/).*/',$test, $extract);
echo "http://www.inchicago.com$extract[0]";
?>

I am having a bit of trouble with this. I am a beginner with regular expressions, so please bear with me. What I am trying to do is match

http://www.mytravelsite.com/states/cities/thiscity/

to

http://www.inchicago.com/

so that when I pass the url through my object

<a href="http://www.mytravelsite.com/states/cities/thiscity/dir0-6/whateverpageisindexed.shtml">title</a>

becomes a clickable link to thats file location that looks like

<a href="http://www.inchicago.com/dir0-6[whicheverisreturned]/whateverpageisindexed.shtml">title</a>

The code

$test="http://www.mytravelsite.com/states/cities/thiscity/0/apage.shtml"; 
preg_match('/\/[^\/]*?\/(?!.*?\/).*/',$test, $extract); 
echo "http://www.inchicago.com$extract[0]";

returns

http://www.inchicago.com/0/apage.shtml

but the numbered dir may fluctuate as well as the returned page. Hopefully that makes sense. How can I make

http://www.mytravelsite.com/states/cities/thiscity/

resolve to

http://www.inchicago.com/

but leave

/0/apage.shtml

alone so that it will be flexible?

Will the grabbed url always be this in the front of the url?- http://www.mytravelsite.com/states/cities/thiscity/
If that is a static part of the url then you could use a str_replace() on that part and set it to nothing so you are left with the last part of the url.

$url = "http://www.mytravelsite.com/states/cities/thiscity/0/apage.shtml";
$new_url = str_replace("http://www.mytravelsite.com/states/cities/thiscity/", "", $url);
echo $new_url;

So to make it

http://www.inchicago.com/dir0-6/somepage.shtml

Would I do this?

$url = "http://www.mytravelsite.com/states/cities/thiscity/"; 
$new_url = str_replace("http://www.mytravelsite.com/states/cities/thiscity/", "http://www.inchicago.com/", $url); 
$endurl = $passedurldata;
echo $new_url.$endurl;

Looks like that should work.

[james438]

<?php
$test="http://www.mytravelsite.com/states/cities/thiscity/0/apage.shtml";
preg_match('/\/{1}[^\/]*?\/{1}(?!.*?\/).*[^\/]$/',$test, $extract);
if ($extract[0]=="") $prefix="http://www.inchicago.com/";
else $prefix="http://www.inchicago.com";
echo "$prefix$extract[0]";
?>

I modified it just a little to account for the possibility that no file name is listed. This will now match

http://www.mytravelsite.com/states/cities/thiscity/0/apage.shtml
http://www.mytravelsite.com/states/cities/thiscity/
http://www.mytravelsite.com/states/cities/thiscity/27/apage.shtml
http://www.anysite.com/stage/theater/0who/apage.shtml

I do not think I fully understand what you are asking for.

How does my earlier example not give you what you are looking for?

Hi James,

Basically there are several hundred indexed items. Since the beginning of the url

http://www.mytravelsite.com/states/cities/thiscity/

needs to be equated to

http://www.inchicago.com/

always.

but the directories 0-6 come after and have several hundred .shtml pages in each.

So I really need to match those urls but leave the last two /dirs/ i.e.(/0/apage.shtml/ might be /1/apage23.shtml) as however they are served back from the query.

Hopefully that is clearer.

In that case it looks like what fastsol1 is suggesting would be better. I hope it helps.
