Two values from same array string?

Hi, here is what I would like to acomplish but cant figure out the proper way to do it:

Basicaly I have a page where I want to display links. To do this, I use a list of URLs from a text file, which I call like so:

$array=file("links.txt");

And then use the following to display each link as list elements:

foreach ($array as $item => $value) {
print "<li><a href=\"http://$value\" class=\"g\"><b>$urlname</b></a>\n";
}

(I dont fully understand how the foreach argument really works but its working. I have no clue what $item should be...but that's not my concern right away.)

So far this works fine. Except for one detail. You see that "$urlname" up there? I would like that to be the link's name obviously. How would I define it in my list of links from link.txt ?

Right now that file is setup like so:

www.web1.com
www.web2.com
www.web3.com

I would like to define $urlname in there as well. I was thinking of setting it up like this:

www.web1.com=link one
www.web2.com=link two
www.web3.com=link three

This way I would define two variables (as seperated by "=") from each string in my array.
Now does anyone have any idea how to do this?
Thank you!

I suggest you to use tabs instead of "=". Makes your links file more readable.

foreach ($array as $line)
if (ereg("^{([^{\t])\t+([^\t])$",}} trim($line), $reOut))
echo "<a href=\"$reOut[1]\" class=\"g\">$reOut[2]</a>\n";

You could also use explode() instead of ereg(), but this allows you do use variable number of tabs, allowing you to have two columns in your links file.

Great, this worked perfectly. However, what do I replace if I wanted something other than Tab to seperate my values?

Thank you!

But, be careful not to include some regular expression meta-char (",", "?", "[", "]", "(", ")",...). Why would you whant to use anything else anyway?!
