display provider name form hostname

[Eric Rechter]

Hi,

I only want to display the provider name from a hostname, so I need to
divide the string to take only de characters from after the before last dot.

For example:

dsl-083-247-088-130.solcon.nl -I only wanna display "solcon.nl"

adsl-dc-4d454.adsl.wana doo.nl -I only wanna display "wanadoo.nl "


I tried with "substr()", but than you have to know the exact positions, and
that's different in a hostname.

Anybody knows if this possible?

kind regards,

Eric

i found this solution:

<?php
$host = "dsl-083-247-088-130.solcon.nl";

$char = 2;
$_count_dot = 0;
while ($count_dot != 2){
$char++;
$dot = substr($host, -$char, 1);
if ($dot == "."){
$count_dot++;
}
}
echo substr($host, -$char+1);
?>

Maybe this is part of a solution:

http://www.php.net/manual/nl/function.parse-url.php

Else, your code shorter:
$string = "dsl-083-247-088-130.solcon.nl";
preg_match('/[^.]+\.[^.]+$/',$string,$matc h);
$host = $match[0];

$hostname = "dsl-083-247-088-130.solcon.nl";
$parts = explode('.', $hostname);
if (count($parts) >= 2)
$provider_name =
$parts[count($parts) - 2] . '.' . $parts[count($parts) - 1];
else
$provider_name = $hostname;

Well, if we're going that way:
$host = implode('.',arr ay_slice(explod e('.',$hostname ),-2));

Hehehe, oneliners are fun to make up, but often a terrible thing in real
code :-). It's usually better to be a bit more verbose to keep the code
legible for future coders. (Even for yourself after a year. I've cursed my
own cryptic code quite often in the past).
