PHP help (was PayPal IPN & LC)

[Richard Miller]

Any ideas why this would not put "this is just a test" into the file 
"dump.txt"?
PayPal is happy with the script. It indicates it has received the 
correct response when it calls this PHP script.
The script is located in my Documents folder on my (dedicated OSX) server.
I can't set that folder to WRITE permissions, so I have to write the 
data to my cgi-bin folder.
I am trying to write the data to the cgi-bin folder via an ftp write 
(the area shown below from <=== to <====).
The cgi-bin folder is all 777 permissions.

Thanks.
Richard


// PHP 4.1

// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';

// file_put_contents("dump.txt", print_r($_POST, true));

/* set the FTP hostname */ <===========
  $user = "rdm2222";
  $pass = "ilanxxxx";
  $host = "65.23.157.7";
  $file = "dump.txt";
  $hostname = $user . ":" . $pass . "@" . $host . "/" . $file;

  /* the file content */
  $content = "this is just a test.";

  /* create a stream context telling PHP to overwrite the file */
  $options = array('ftp' => array('overwrite' => true));
  $stream = stream_context_create($options);

  /* and finally, put the contents */
  file_put_contents($hostname, $content, 0, $stream); <===========
