Image Downloading small problem

[Anthony2oo5]

Hey,

I'm trying to remotely download an image to my server via the web and an URL that the user inputs. I have managed to do this with a cron job, and write the file to the system no problem.

My problem lies with viewing the image, the image wont show. I looked at the source code of the image and it seems to be because PHP is writing data to the top of the file,

HTTP/1.1 200 OK Set-Cookie: JCPARPT=ZLNIZZSSRVDXECKKMO; path=/ Content-Length: 9566 Content-Type: image/jpeg Last-Modified: Fri, 05 May 2006 22:14:11 GMT Accept-Ranges: bytes ETag: "8811773c9170c61:9be" Server: Microsoft-IIS/6.0 X-Powered-By: ASP.NET Date: Wed, 13 Jun 2007 14:13:08 GMT ÿØÿà�JF

Is there anyway I can stop PHP doing this, or remove it from the code with some sort of preg_match before writing it to disk.

Or is there an alternative method I should be using?

thanks in advance for any time and help.

what is your code for getting the image?

[PHP]<?php
include ('includes/functions.php') ;
$Error = "";
$UploadDIR = 'images/';
$ShortenTo = 15;

function RemoteGet($addr ess) {
// Connect to the google website to find the millage
$ch = curl_init();
curl_setopt($ch , CURLOPT_URL, $address);
curl_setopt($ch , CURLOPT_HEADER, 1);
curl_setopt($ch , CURLOPT_RETURNT RANSFER, 1);
$data = curl_exec($ch);
curl_close($ch) ;
echo $data;
// Make a random string
$RandomString = RandomString(4) ;
// Get the file extention to put back later
$FileExt = GetFileExt($add ress);
// Make it lowercase
strtolower($Fil eExt);
// Check its the correct extention
if (($FileExt == 'jpg') || ($FileExt == 'gif') || ($FileExt == 'png') || ($FileExt == 'bmp')) {
// Remove the file extention from the file
$file = RemoveExtension ($address);
// Now clean anything thats not alphanumeric
$file = preg_replace('`[^a-z0-9]`i', '', $file);
// Shoerten the filename
$file = substr($file, 0, $ShortenTo);
// Put the extention back on
$file = $file . '.' . $FileExt;
// Set the path
$uploadfile = $UploadDIR . $RandomString . $file;
// The filename is
$FileName = $RandomString . $file;
// Write the file to disk
$fh = fopen($FileName , 'w') or die("can't open file");
fwrite($fh, $data);
fclose($fh);
return "http://" . $_SERVER[HTTP_HOST] . "/Image-" . $FileName;
}
}

echo RemoteGet("http ://google.com/images/google.gif");

?>[/PHP]

Rather than perform a curl call (which is likely where the headers are coming from), just fopen the URL directly.

Will try that in a sec, thanks.

Was going to use that but thought curl was quicker.

Let us know how it turns out.

[Anthony2oo5]

Ok, now it sort of works lol. But the file only seems to half download, Check here:

[ur]http://piczy.net/Image-MCTWK.gif[/url]

I changed the Cron job with the following:

[PHP]$fh = fopen($address, 'r') or die("Can't open file");
$data = fread($fh, 524288000000);
fclose($fh);[/PHP]

Note all the 0000000 at the end was me upping the limit to see if thats why it was stopping. But it wasnt.

Any ideas? This must be possible and cant be this hard lol.

Thanks for your time.

[Motoma]

Wait!

Am I correct in my understanding that you are using cron to execute a PHP script?

[pbmods]

Try using file_get_conten ts, or better yet, fread instead.

[Anthony2oo5]

Wait!

no, I have the above code in a php file, then just run the file directly. I had curl to get the image (i may have said cron before sorry), but changed it to fopen as you said.

Will have a go of file get contents.

[Motoma]

Straight from PHP.net

When reading from anything that is not a regular local file, such as streams returned when reading remote files or from popen() and fsockopen(), reading will stop after a packet is available. This means that you should collect the data together in chunks as shown in the examples below.

[code=php]
<?php
$handle = fopen("http://www.example.com/", "rb");
$contents = '';
while (!feof($handle) )
{
$contents .= fread($handle, 8192);
}
fclose($handle) ;
?>
[/code]

YEY, file get contents works great thanks very much for all the help.

May I have one request?, can I have the code from my second post removed please? Everything else can stay.

Once again thanks all.

We don't work like that...I'm sure something could be censored out if you need it to.

[Anthony2oo5]

Just didn't want hackers knowing my script. can you censor like 4 and 40 please.

Thanks :)

[Motoma]

Done!

Come back with any more questions.
