PHP - Http:// Wrapper Is Disabled In The Server?

is there anything i can use in replace of it to write permissions with
system("chmod -R 777 \"$SET0/comments\" ");

I have no idea why it's doing it. I know I'm missing something, but everything looks right to me. When you submit the registration form it just does the error, and properties say its the process page, so this code below. Sorry posting it all, I'm just not sure period.

Code: [Select]
<?php
require('connect.php');

//check all the posted info
function getInfo() {
$error = array();
$fname = validateFirstname($_POST['fname']);
$lname = validateLastname($_POST['lname']);
$uname = validateUsername($_POST['uname']);
$email = validateEmail($_POST['email']);
$password = validatePass($_POST['password1'], $_POST['password2']);
$phone = validatePhone($_POST['phone']);

//check for errors
error();
}
function validateFirstname($str) {
//This allows just alpha characters and must be at least 2 characters.
if (preg_match('/^[a-zA-Z0-9]{2,}$/',$str)) {
return  preg_match('/^[a-zA-Z0-9]{2,}$/',$str);
} else {
$error[] = 'Please enter a valid first name!';
}

}
function validateLastname($str) {
//This allows just alpha characters and must be at least 2 characters.
if (preg_match('/^[a-zA-Z0-9]{2,}$/',$str)) {
return  mysql_real_escape_string($str);
} else {
$error[] = 'Please enter a valid last name!';
} 

}
function validateUsername($str) {
//connect to database
$link = mysql_connect($db_host, $db_user, $db_pass);

I need to check (from a Debian server to a Mac CLIENT (not server) machine) to see if a file exists on the file system...not an http server.

Here's what I've tried (based on reading at http://www.php.net/manual/en/function.ssh2-exec.php)

Code: [Select]
<?php
function check_remote_files($username, $hostname, $remote_file)
{
$connection = ssh2_connect($hostname, 22, array('hostkey'=>'ssh-rsa'));

if (ssh2_auth_pubkey_file($connection, $username,
                          '/root/.ssh/id_rsa.pub',
                          '/root/.ssh/id_rsa', '')) 
{
echo "Public Key Authentication On Server #2 Successful\n";
}

$url = "if ssh $hostname stat $remote_file \> /dev/null 2\>\&1";
$stream=ssh2_exec($connection,$url);
    stream_set_blocking( $stream, true );
    $cmd=fread($stream,4096);
fclose($stream);

$stream=ssh2_exec($connection,"then");
    stream_set_blocking( $stream, true );
    $cmd=fread($stream,4096);
fclose($stream);

$stream=ssh2_exec($connection,"echo File exists");
    stream_set_blocking( $stream, true );
    $cmd=fread($stream,4096);
fclose($stream);

$stream=ssh2_exec($connection,"else");
    stream_set_blocking( $stream, true );
    $cmd=fread($stream,4096);
fclose($stream);

$stream=ssh2_exec($connection,"echo Not found");
    stream_set_blocking( $stream, true );
    $cmd=fread($stream,4096);
fclose($stream);

$stream=ssh2_exec($connection,"fi");
    stream_set_blocking( $stream, true );
    $cmd=fread($stream,4096);
fclose($stream);

}
?>

NOTHING happens after the echo of Public Key Authentication On Server #2 Successful.

I'm running this script from a bash shell.

Any ideas what might be wrong?

Thanks.

Trying to run a simple program that, when submitted, stores the username and password as cookies.  When clicking Submit, I get the error  "HTTP Error 405 - The HTTP verb used to access this page is not allowed". If the username and password fields are left blank when submitting it's suppose to give a message to enter a username and password, but, I still get that error message.

How do I only redirect the page when index.php is present?
