I changed the read function to:
public function receiveFile($remote_file, $local_file)
{
$sftp = $this->sftp;
$stream = @fopen("ssh2.sftp://$sftp$remote_file", 'r');
if (! $stream)
throw new Exception("Could not open file: $remote_file");
$size = $this->getFileSize($remote_file);
$contents = '';
$read = 0;
$len = $size;
while ($read < $len && ($buf = fread($stream, $len - $read))) {
$read += strlen($buf);
$contents .= $buf;
}
file_put_contents ($local_file, $contents);
@fclose($stream);
}
public function getFileSize($file){
$sftp = $this->sftp;
return filesize("ssh2.sftp://$sftp$file");
}
ssh2_sftp
(PECL ssh2:0.10-0.9)
ssh2_sftp — Initialize SFTP subsystem
Description
resource ssh2_sftp
( resource $session
)
Request the SFTP subsystem from an already connected SSH2 server.
Return Values
This method returns an SSH2 SFTP resource for use with all other ssh2_sftp_*() methods and the ssh2.sftp:// fopen wrapper.
Examples
Example #1 Opening a file via SFTP
<?php
$connection = ssh2_connect('shell.example.com', 22);
ssh2_auth_password($connection, 'username', 'password');
$sftp = ssh2_sftp($connection);
$stream = fopen("ssh2.sftp://$sftp/path/to/file", 'r');
?>

Not sure if this is a bug of some kind of security feature.
When reading files using ssh2.sftp anything inside php tags is inexplicably stripped.
foo.php
one
<?
echo 'two';
?>
echo 'three';
$stream = fopen("ssh2.sftp://$sftp$file", 'r');
echo filesize("ssh2.sftp://$sftp$file"); //CORRECT
echo fread($stream, filesize("ssh2.sftp://$sftp$file")); //prints "onethree"
Not sure why this happens and haven't found a workaround.

I added some functionality for scanning the filesystem and receiving and deleting files.
class SFTPConnection
{
private $connection;
private $sftp;
public function __construct($host, $port=22)
{
$this->connection = @ssh2_connect($host, $port);
if (! $this->connection)
throw new Exception("Could not connect to $host on port $port.");
}
public function login($username, $password)
{
if (! @ssh2_auth_password($this->connection, $username, $password))
throw new Exception("Could not authenticate with username $username " . "and password $password.");
$this->sftp = @ssh2_sftp($this->connection);
if (! $this->sftp)
throw new Exception("Could not initialize SFTP subsystem.");
}
public function uploadFile($local_file, $remote_file)
{
$sftp = $this->sftp;
$stream = @fopen("ssh2.sftp://$sftp$remote_file", 'w');
if (! $stream)
throw new Exception("Could not open file: $remote_file");
$data_to_send = @file_get_contents($local_file);
if ($data_to_send === false)
throw new Exception("Could not open local file: $local_file.");
if (@fwrite($stream, $data_to_send) === false)
throw new Exception("Could not send data from file: $local_file.");
@fclose($stream);
}
function scanFilesystem($remote_file) {
$sftp = $this->sftp;
$dir = "ssh2.sftp://$sftp$remote_file";
$tempArray = array();
$handle = opendir($dir);
// List all the files
while (false !== ($file = readdir($handle))) {
if (substr("$file", 0, 1) != "."){
if(is_dir($file)){
// $tempArray[$file] = $this->scanFilesystem("$dir/$file");
} else {
$tempArray[]=$file;
}
}
}
closedir($handle);
return $tempArray;
}
public function receiveFile($remote_file, $local_file)
{
$sftp = $this->sftp;
$stream = @fopen("ssh2.sftp://$sftp$remote_file", 'r');
if (! $stream)
throw new Exception("Could not open file: $remote_file");
$contents = fread($stream, filesize("ssh2.sftp://$sftp$remote_file"));
file_put_contents ($local_file, $contents);
@fclose($stream);
}
public function deleteFile($remote_file){
$sftp = $this->sftp;
unlink("ssh2.sftp://$sftp$remote_file");
}
}

if anyone is interested on how to get a directory listing:
$SSH_CONNECTION= ssh2_connect('shell.example.com', 22);
ssh2_auth_password($SSH_CONNECTION, 'username', 'password');
//-------------------------------------------------------------------
//this function finds all files within given directory and returns them
function scanFilesystem($dir) {
$tempArray = array();
$handle = opendir($dir);
// List all the files
while (false !== ($file = readdir($handle))) {
if (substr("$file", 0, 1) != "."){
if(is_dir($file)){
$tempArray[$file]=scanFilesystem("$dir/$file");
} else {
$tempArray[]=$file;
}
}
}
closedir($handle);
return $tempArray;
}
//-------------------------------------------------------------------
$sftp = ssh2_sftp($SSH_CONNECTION);
//code to get listing of all OUTGOING files
$dir = "ssh2.sftp://$sftp/outgoing";
$outgoing = scanFilesystem($dir);
sort($outgoing);
print_r($outgoing);

The sftp class provided by David Barnes works great. However, if you get errors about fopen and it failing to open a stream, try the fully qualified path on the remote server.
For example, if you are uploading a file to /Users/username/Sites/file.txt this may not work:
<?php
try {
$sftp = new SFTPConnection("localhost", 22);
$sftp->login("username", "password");
$sftp->uploadFile("/tmp/to_be_sent", "Sites/file.txt");
}
catch (Exception $e) {
echo $e->getMessage() . "\n";
}
?>
but this will:
<?php
try {
$sftp = new SFTPConnection("localhost", 22);
$sftp->login("username", "password");
$sftp->uploadFile("/tmp/to_be_sent", "/Users/username/Sites/file.txt");
}
catch (Exception $e) {
echo $e->getMessage() . "\n";
}
?>
Don't assume that since you are connecting as that user that you are starting in its home space.
Another possible option is that you need to use http://us.php.net/manual/en/function.ssh2-sftp-mkdir.php first to make the directory if it does not exist already, and then upload the file into it.

Here is an example of how to send a file with SFTP:
<?php
class SFTPConnection
{
private $connection;
private $sftp;
public function __construct($host, $port=22)
{
$this->connection = @ssh2_connect($host, $port);
if (! $this->connection)
throw new Exception("Could not connect to $host on port $port.");
}
public function login($username, $password)
{
if (! @ssh2_auth_password($this->connection, $username, $password))
throw new Exception("Could not authenticate with username $username " .
"and password $password.");
$this->sftp = @ssh2_sftp($this->connection);
if (! $this->sftp)
throw new Exception("Could not initialize SFTP subsystem.");
}
public function uploadFile($local_file, $remote_file)
{
$sftp = $this->sftp;
$stream = @fopen("ssh2.sftp://$sftp$remote_file", 'w');
if (! $stream)
throw new Exception("Could not open file: $remote_file");
$data_to_send = @file_get_contents($local_file);
if ($data_to_send === false)
throw new Exception("Could not open local file: $local_file.");
if (@fwrite($stream, $data_to_send) === false)
throw new Exception("Could not send data from file: $local_file.");
@fclose($stream);
}
}
try
{
$sftp = new SFTPConnection("localhost", 22);
$sftp->login("username", "password");
$sftp->uploadFile("/tmp/to_be_sent", "/tmp/to_be_received");
}
catch (Exception $e)
{
echo $e->getMessage() . "\n";
}
?>
