how to pass argument in php for executing shell command?

Question

Here is the program listed below. I am trying to run the shell command from php so I have written the following code:

<?php    
$argument1 = $argv[1];    
$output = shell_exec('sudo whois ');    
echo "<pre>$output</pre>";    
?>

But every time I execute the command it get executed but doesn't display output. Only shows the option.

My command in shell is php filename.php google.com

You aren't using passed argument in your command. You need to use the argument in whois command:

<?php    
$argument1 = escapeshellarg($argv[1]);  
$output = shell_exec('whois '. $argument1);    
echo "<pre>$output</pre>";    
?>

PS: whois can tun without sudo also.

don't forget to shell-escape the input :-)

Thanks @anubhava for your help and what if i want to call these from web instead from command line...

Just replace above script with: echo "<pre>" . shell_exec('whois '. $_GET['url']) . "</pre>"; and call your script as: http://domain.com/shell.php?url=google.com

You need to make sure to use GET method in form action. Also create script as I commented above and access the direct URL as http://domain.com/shell.php?url=google.com once that is working then move on to your other script with submit button and form. If nothing works post your both PHP scripts in question so that I can debug it.
