[SOLVED] backtick operator problems

[Motlive]

Hi All,

 

a newbie for you all to abuse

 

I have been trying to get my head around this for a while and it just wont budge.

 

i have a debian machine that runs:

 

	<?php
$output = `/usr/bin/host -t ns $query`;

$find [] = "Host $query not found: 3(NXDOMAIN)";
$find [] = "$query name server";
$replace [] = " Domain Not Found - Please make sure you've spelt it correctly";
$replace [] = "";

$output =  str_replace($find, $replace, strtolower( trim( $output ) ) ); 

if (preg_match("^[a-z0-9\:\.\-]+$^", "$output $query"))
{
	echo "Name Servers:<pre>$output</pre>";
}		
elseif ($domain == ""){
	echo "";
}
else {
	echo "You have entered an invalid domain name, do not enter 'http://' or 'www.'";
}
?>

 

Now i have moved over to a Windows Server running IIS instead of Apache and I dont know how to make the above work in that enviroment :S

 

any guidance would be much appreciated.

Why not you use exec()

[neel_basu]

And what actually you wanna Do ??

I dont understand where i am meant to point the exec() function towards.

 

I have a page which you enter in a domain and it will give you info on its name servers, MX records A records and the WHOIS. so simple DNS lookups really.

<?php
$output = `/usr/bin/host -t ns $query`;

$find [] = "Host $query not found: 3(NXDOMAIN)";
$find [] = "$query name server";
$...... and so on

 

bugger.. sorry i missed out the command on my first post:

Exec is never a good idea to use, and it's better to be avoided for security reasons.

 

For your issue, you may want to look around PHP.net and see if there are any bugs related to your specific system.  Looking at the code I don't see anything off hand that might be messing it up, it looks fine, maybe there is a type of bug with one of the functions you are using that is only a bug on that specific system, you can check into it over at php.net by going through there list of bug's, or running a few google searches on "php problems on (insert operating system here)"

 

Based on your last post, if you are wanting to do DNS lookups.

http://www.google.com/search?source=ig&hl=en&q=DNS+lookup+API+with+php&btnG=Google+Search

You will find a lot of stuff there, that will help you find out everything you need, on making it work.

Don't use the exec function, I am warning you before it's too late, especially if you are using it with user input, you will end up finding out why I advised you not to if you try and use it.

This command...

 

/usr/bin/host -t ns $query

 

Is never going to hold up in windows, it is a *nix command. I'm not sure whats available on windows, but you will need to find an equivelent to the host command, I'm just not sure one would exist.

That seems to be the conclusion I am coming to as well.. bugger.

This is all I could find, hopefully it helps it was as close as I could come to finding something helpful.
