Dear Comrades,
Can someone please explain why this is script is not working on my win2k
box with PHP 4.3.4?
<?php
$email="fabio.ottolini@xxxxxxxxx";
list($alias, $domain) = split("@", $email);
$command = "nslookup -type=mx $domain";
exec ( $command, $result );
$i = 0;
while ( list ( $key, $value ) = each ( $result ) ) {
if ( strstr ( $value, "mail exchanger" ) ) { $nslookup[$i] = $value;
$i++; }
}
while ( list ( $key, $value ) = each ( $nslookup ) ) {
$temp = explode ( " ", $value );
$mx[$key][0] = $temp[3];
$mx[$key][1] = $temp[7];
$mx[$key][2] = gethostbyname ( $temp[7] );
}
array_multisort ( $mx );
print_r($mx);
print "<br><br>";
print $mx[0][1];
?>
The same script works fine in another win2k box running PHP version 5. Strange
is that if I add print $result; right after exec ( $command, $result );
nothing is printed. When the script runs on the machine that works it prints
Array obviously. So, my guess is that $command is never being executed.
BTW, PHP is not running on safe_mode and the nslookup command works fine
on both machines.
Any help would be very much appreciated.
Kind Regards,

I tested your script on my Apache server running PHP 5.0 on WinXPPro...
it gives these errors:
----

Ok, after some messing around I fixed it:
Replace
$command = "nslookup -type=mx $domain";
with
$command = "nslookup $domain";
