download a file to my server?

anders2000

Hí there guys, I am writing a script to download a image from a url (ie http://server.com/image.jpg) and then to save it on my server. The problem is that I am using php4.0 something and I cant use copy coz it doesnt handle urls yet.

So, I thing I have to use fopen and such, but i just dont get it right. I have never used fopen and all those functions before. Heres my code:

 $imageDir = "../../integrated/images/gallery/TEMP";
            $image = fopen($the_url, r);

            $read1 = fread($image, 10000000) OR DIE ("error 1");

            $fileImage = $imageDir.".jpg";

            $image2 = copy($read1, $fileImage);
            $the_file = $fileImage;

Since this doesn't work at all, I'd be happy if someone could give me and example code that does work (sorry for beeing cheeky, but i'm a newbie). I have looked through the manual for hours, but without result.

I am using a form with a text-type inputbox for the url.

Cheers,
anders

Try this function...

function dlImage($strUrl)
{
        $fpImage = fopen($strUrl,'r');
        $strContent = fread($fpImage,1000000);
        $arrParts = explode('/',$strUrl);
        $arrParts = array_reverse($arrParts);
        $fp = fopen($arrParts[0],'a+');
        if($fp)
        {
                fwrite($fp,$strContent);
                echo 'Image downloaded.';
        }
}

Usage...

dlImage('http://www.1337.is/gegt.gif');

try using file function



$url = "http://server.com/image.jpg";
$image_content = file($url);
$image = join("",$image_content);

$fp = fopen($filename,'w');
if($fp)
{
     fwrite($fp,$$image);
}
fclose($fp);

Looks more-or-less fine to me - including for PHP4 (do you mean 3?). I'd put r in quotes, myself, and I'd use a loop to fread a sensible amount while I'm !feof(), but apart from that it looks okay and I don't see why it would "not work at all".

Unless $the_url doesn't contain what it's supposed to (i.e., a URL).

But depending on where the file ends up, it's pretty insecure: what if someone typed in the name of a file on your own server? "/etc/.passwd", for example?

And do you really want to copy it to "../../integrated/images/gallery/TEMP.jpg"? I ask, because I don't see why you split that filename into two pieces.
