Why is localhost added to all my links ?

[Hal Halloway]

Not sure if this is a php, mysql, or apache issue. I use win2k and I
have AMP on my system as a localhost. I use this to test PHP/MYSQL
scripts I write on my local PC.

I render a URL w/PHP by reading the URL string from a mysql field, eg.
on the php web page it shows as eg. www.yahoo.com link

But when I click the link I see that "localhost" is added to the URL
and it goes nowhere. ie. it get localhost added to the front -
localhost/www.yahoo.com

Is there a setting somewhere so that the link is exactly what the link
is and localhost is not added.

Thanks

Relative URLs are expanded with the current hostname. If you want to
link to external servers the URL has to start with http(s)://.

When you construct the anchors without the "http://" prefix, all the targets
are expected to be on the same server.

looks like PHP has a couple of rules:

1. if you prefix a URL with http:// or just a /, then it leaves it alone.

i.e "http://www.happyhappyb unnies.com"
"/showerror.php?e rr=342"


2. if you do neither of these, it prefixes them with a host name and /.

best choice would be to prefix full URLs with http:// and relative URLs
with /.

PHP does have a mechanism via which you can control what markup elements
it modifies on output, which somehow ties into the url_rewriter.ta gs entry
in the php.ini file. i haven't studied this too much, so i'm not 100%
certain how it works.

good ruck!

It's not a PHP issue.

The user agent (browser) expands URLs if necessary, not the server. Have
a look at the generated HTML to see what PHP did send to the browser.

This only applies to session handling.
