Saving a remote Image

Anon

Grrr. Thsi thing is driving me insane. What I am tryign to do is simply retrieve an image located on another server via HTTP and then save it in a directory identical to the one one the remote server. Is this possible? I woudl it should be. This si what i am working with. Someoen please correct me where i am wrong.

function getimg($img,$path){
$fp = fopen("http://www.remotesite.com/images/$img", "b");

if($fp){

	fputs ($fp, $img);
				    		fclose ($fp);

	return true;
}else{
	echo $errstr;
	return false;
}

}

I am not getting any errors, and it returns true, but no image is saved that i can see.

Your code looks way incomplete!

You open the input file but you don't open the output file.
Your fputs() function that is ment to write the result is actually trying to write to the input file.
You're trying to write the result but you never read it in the first place.

At a rough guess I think the code should look something like this:

function getimg($img,$path){
$infp = fopen("http://www.remotesite.com/images/$img", "b");
if($infp){
$outfp = fopen($path, "w");
while(!feof($infp)) {
$buffer = fread($infp, 50000);
fwrite($outfp, $buffer, strlen($buffer));
}
fclose($infp);
fclose($outfp);
return true;
}else{
echo $errstr;
return false;
}
}

Thank you. I am nto sure if that will work for me or not. I am nto getting any errors but i cannto open a file for writeing. IT must be some kind of server configuration. I know the PHP has safemode turned on. Would effect this?

Yeah, I should have mentioned that the web server will need write access to the directory that you're trying to create the new image in. This usually isn't the case, so contact the hosting company and ask them to set this up for you.
