Copy Non-Text file from One Server to Another Issues

[Alice Wei <ajwei@xxxxxxxxxxxxx>]

Hi, 

   I have a simple code as shown in the following:

<?php

//original file
$file = "http://remote_server/copy/play.txt";;
$file2 = "http://remote_server/copy/test.jpg";;
$file3 = "http://remote_server/copy/sample.pdf";;

//directory to copy to (must be CHMOD to 777)
$copydir = ".";

$data = file_get_contents($file);
$file2 = fopen($copydir . "/play.txt", "w+");
fputs($file2, $data);
fclose($file2);

$data2 = file_get_contents($file2);
$file3 = fopen($copydir . "/test.jpg", "w+");
fputs($file3, $data2);
fclose($file3);

$data3 = file_get_contents($file3);
$file4 = fopen($copydir . "/sample.pdf", "w+");
fputs($file4, $data3);
fclose($file4);

$data5= file_get_contents("play.txt");
echo $data5 . "<br>";

$data6= file_get_contents("test.jpg");
echo $data6 . "<br>";

$data7= file_get_contents("sample.pdf");
echo $data7 . "<br>";

?> 

The first  one, $file, has no problems, and I did get the contents copied correctly. However, the second and third one, I get this error: 

Warning: file_get_contents() expects parameter 1 to be string, resource 
given in C:\Inetpub\wwwroot\test\hello.php on line 
18
./test.jpg 
Warning: file_get_contents() expects parameter 1 to be string, resource 
given in C:\Inetpub\wwwroot\test\hello.php on line 
25
./sample.pdf

I notice that the empty file gets created correctly, but I cannot put in the file contents. If file_get_contents only supports text, could anyone please give me some suggestions on what type of function I should use to put in the file contents so that it is readable?

Thanks in advance.

Alice
