linux - passing a variable from php to bash

Question

I cannot seem to get a variable passed to my bash script from php. $uaddress and $upassword come up empty no matter what I try.

********************* bash ****************

#!/bin/bash -x
useraddress=$uaddress
upassword=$upassword
ssh -p 222 -6 2400:8900::f03c:91f:fe69:8af "/var/www/localhost/htdocs/postfixadmin/scripts/postfixadmin-cli mailbox add" $useraddress --password $upassword --password2 $upassword  .ssh

********** php ****************

<?php
$upassword = 'test1234'; $uaddress = 'mytestuser@tpccmedia.com';
$addr = shell_exec('sudo /home/tpccmedia/cgi-bin/member_add_postfixadmin 2>&1'); echo $uaddress; echo $upassword;
//$addr = shell_exec('ssh -p 222 -6 2400:8900::f03c:91f:fe69:8af /var/www/localhost/htdocs/postfixadmin/scripts/postfixadmin-cli mailbox add; echo $useraddress; --password; echo $upassword; --password2; echo $upassword; .ssh');
echo "<pre>$addr</pre>";
var_dump($addr);
?>

*********** output and debug ************

You need to pass the variables as arguments to the shell script, and the shell script has to read its arguments.

So in PHP:

$useraddress = escapeshellarg('mytestuser@tpccmedia.com');
$upassword = escapeshellarg('test1234');
$addr = shell_exec("sudo /home/tpccmedia/cgi-bin/member_add_postfixadmin $useraddress $upassword 2>&1");

and in the shell script:

useraddress=$1
upassword=$2
