How to open the file on the client?

kychen

My code:
shell_exec("touch /var/www/temp/".urlencode($home_picture));
$fp_web = fopen("/var/www/html1/temp/".urlencode($home_picture), "wb");
if (!$fp_web)
{
echo "open the server file /var/www.thml/temp/".$home_picture."failure¡I";
exit;
}
$fp_remote = fopen(htmlspecialchars("c:\image\").urlencode($home_picture), "rb");
if (!fp_remote)
{
echo "open the client fule c:\image\".$home_picture."failure¡I";
exit;
}
while (!feof($fp_remote))
{
$content = fread($fp_remote, 1);
fputs($fp_web, $content, 1);
}
fclose($fp_web);
fclose($fp_remote);
but when the codes operate the $fp_remote, it shows warning no such files. how can I solve it?

Here's a rule of thumb. You do not have access to the clients file system.. When you execute this:

$fp_remote = fopen(htmlspecialchars("c:\\image\\").urlencode($home_picture), "rb");

PHP is attempting to open a file on the local file system which in your case looks like a linux file system.

You can only look at files on a client mchine using FTP, which would require the client to have an FTP sever running on their PC. You can however ask a client to submit you a file. You can do this with a simple HTML form:

<form action="file-upload.php" method="post" enctype="multipart/form-data">
 Send these files:<br>
 <input name="userfile" type="file"><br>
 <input type="submit" value="Send file">
</form>

When the user presses the submit button the file is copied from their computer to your computer. You can then get at this file using the move_uploaded_file() function. The file information is contained in the $_Files[] global array. The following link contains more information on file uploads.

Hope this helps.

Just as a side not that can't be a nix system because only Windoze uses the C:\ type structure nix uses things like /usr and /lib and things like that. 😃

Thanks for your reply.

Hope this helps.

But I ever try to use the form-POST method, I find the file upload can't be used in php & HTML code.
<body background='/temp/<?php echo $home_picture; ?>' style='background-repeat:no-repeat;background-attachment:fixed'>
It displays on the screen is nothing, and it's file size is bigger than the original one. Why?
But very strangely, I use CuteFtp32 to transfer JPEG file. It works.
Using form-POST method, It doesn't work.
So I try another way.

I haven't got a clue what you are trying to do. But post the code thats gone wrong. Transfering files using HTTP should yield exactly the same results as using FTP.

I think it over. I really find a good way.

First you must make your client machine have www service, then coding like follows:
$fp_remote = fopen(htmlspecialchars("http://".$HTTP_SERVER_VARS['REMOTE_ADDR']."/").urlencode($home_picture), "rb");

Now, it works.
