Passing variable from one function to another

[Anon]

Im not sure if this is even the correct way of doing this but hey I'm learning.

Ok I want to pass info from one function to another.

Heres the first function:

function server_location($server){
switch ($server){
case "com": echo ("www.geektools.com");
break;
case "org": echo ("www.geektools.com");
break;
case "net": echo ("www.geektools.com");
break;
}
}

Here is how I call it:
When the form is submitted the variable "$domain" contains : whatever.com

This ($server = explode (".", $domain);
) gives me the "com" to send to the function server_location
<?
$server = explode (".", $domain);
$server= (server_location("$server[1]"));
?>

When the function returns the results it "prints" the domain www.geektools.com.
What I want this to do is:

1.check to see if when the form is submitted what domain ext it has.

If it has net, org whatever; assign the correct domain to the variable $server and pass it to the second function. But all I can figure out at this moment is how to print it.

Could anyone help?

Thanks

presumably, what you want is the TLD (top level domain), i.e. the characters following the last period in the string. I'd use a regex (I'm just like that) to get that, so supposing you want two functions:

function get_tld($server) {
ereg(".([:alpha:]+)$", $server, $tld);
return $tld[1];

/explanation: the regex says "look for a . followed by one or more alphabetic characters at the end of the string $server; put the results of the first string that matches the (one or more letters) part into $tld[1] /
}

function server_location($tld) {
switch ($tld) {
case "net":
// blah blah
break;
case "org":
//blah blah

}

then you could call the whole thing in one fell swoop with "server_location(tld($input));" However, if you don't need to get the tld anywhere else, you're probably better off making it one function, i.e. have server_location extract the tld itself.

HTH,
