Why foreach returns only the last value from an array correctly? Solved! Thanks to Anand Bhatnagar!

Question

domains.txt contain two lines with:
php.net
sololearn.com

So, I want ip next to every domain, but

<?php
$domains=file('domains.txt');
foreach($domains as $domain)
{
$ip = gethostbyname($domain);
echo $domain. " " . $ip .'<br>';
}
?>

the output is:
php.net php.net
sololearn.com 184.168.221.12

I need output:
domain -> IP (not domain again)
domain -> IP

Any recommendation? Thank You SoloLearners!

Maybe I have the problem how to get the domains from remote file to an array.

Answer 1

try with a trailing dot in php.net -

php.net.
sololearn.com

If you do a gethostbyname() and there is no trailing dot after a domainname that does not resolve, this domainname will ultimately be appended to the server-FQDN by nslookup.
(SOURCE- php.net)

note:
may be there is some problem with your file domaina.txt
because while trying this using array it works perfectly.
$domains= ["php.net", "sololearners.com"];

Answer 2

Thank You Anand Bhatnagar!!!
I think there is no problem with the domains.txt.
I tried to use .,;"- behind the php.net and it is not working
But yes, when I manually create an array, it is OK:

$domains=['php.net', 'sololearn.com'];
foreach($domains as $domain)
{
$ip = gethostbyname($domain);
echo $domain. " " . $ip .'<br>';
}
?>
That's it!!!
php.net 72.52.91.14
sololearn.com 184.168.221.12

Maybe I have the problem how to get the domains from remote file to an array.

You are Great Anand, Thanks again!
