Passing variable from PHP to bash script
I am totally new to PHP and I am trying to create a script that will as a user for a hostname and then use the "hostname" variable to generate a report using REST API.

I am able to create the html script and php script to GET the "hostname" but I am having trouble passing the hostname variable to the bash script which generates the report using REST API.

This is the html script
Code:
<html>
<body>

<form action="test.php" method="get">
Enter Hostname: <input type="text" name="hostname"><br>
<input type="submit">
</form>

</body>
</html>

This is my php script

Code:
Hostname to Query is <?php echo $_GET["hostname"];

$hostname = $argv[1];

#echo "This is $hostname\n";

#$result = shell_exec('/var/www/html/scripts/REST-API/dpa_reports.sh ' . $hostname);
$result = shell_exec('/var/www/html/scripts/REST-API/dpa_reports.sh ' . $hostname);

echo $result;

?><br>

if I do the following from the command line it passes the "hostname" variable to the bash script dpa_report.h script fine. But when I submit the "hostname" from my browser it does not pass the variable...

this command line works

Code:
php test.php hostname-test

ssh-argv0

SSH-ARGV0(1)						    BSD General Commands Manual 					      SSH-ARGV0(1)

NAME

     ssh-argv0 -- replaces the old ssh command-name as hostname handling

SYNOPSIS

     hostname | user@hostname [-l login_name] [command]

     hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
     [-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]

DESCRIPTION

     ssh-argv0 replaces the old ssh command-name as hostname handling.	If you link to this script with a hostname then executing the link is
     equivalent to having executed ssh with that hostname as an argument.  All other arguments are passed to ssh and will be processed normally.

OPTIONS

     See ssh(1).

FILES

     See ssh(1).
