How to get remote file using sockets

hiberphoptik

I have a project that requires I retrieve document(s) from a remote server via TCP/IP and the following script seems to allllmost work:

The issue I am running into is that PHP opens the file and then displays it's binary garbage in the browser screen.

how can i actually retrieve/download the file rather than just display its contents to the browser? I cannot use ftp, sftp, scp due to the custom app that I am connecting to (written in delphi and running on a windows server)

<?php

set_magic_quotes_runtime(false);

$fp = fsockopen("xxx.xxx.xxx.xxx", 6000, $errno, $errstr, 30); 
if (!$fp) {
    echo "$errstr ($errno)<br />\n";
} else {
		$out = "USER=username=";
		$out .= "18=GET=filename.tif";

fwrite($fp, $out);
while (!feof($fp)) {
    echo fgets($fp, 128);
//fgets($fp, 128);
   	//fread($fp, 1024);
    //readfile($fp);
    //fopen($fp, "r");
    //file($fp);
    //file_get_contents($fp);
}
fclose($fp);
}
?>

as you can see i have tried other file manipulation functions with no luck but using sockets and doing file functions is new to me so I am hoping someone out there has done this before or may have some insights

You could use [man]header/man to output a binary file.

<?php // make sure there is nothing, including newlines, before the opening tag
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename="output"'); // change to desired name
header('Content-Transfer-Encoding: binary');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
//rest of code...
exit; // make sure no extraneous characters output such as newlines outside of PHP tags
?>

hey it asks me to save the file... however it just downloads to a certain point and then sits forever never actually saving the file and i have to click cancel 🙁

im begining to think that its simply not possible to retreive files using a web interface to this system
