If you have allow_url_fopen set to true:

$url = 'http://example.com/image.php';
$img = '/my/folder/flower.gif';
file_put_contents($img, file_get_contents($url));

Else use cURL:

$ch = curl_init('http://example.com/image.php');
$fp = fopen('/my/folder/flower.gif', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_exec($ch);
curl_close($ch);
fclose($fp);

Thanks bro, your code help me to solve the problem. But could u pls help me to make the script automated .I mean when a new gif image come to the url (“example.com/image.php”) then our script automatically fetch the new image and store it to my directory? – riad Apr 7 '09 at 8:26

And how do you know, that the new image "came"? – vartec Apr 7 '09 at 8:37

I think riad means using a $_GET variable containing the URL of the image http://example.com/fetch-image.php?url=http://blabla.com/flower.jpg. In the case of this example, you could just call $_GET['url'] in your PHP script, like so: $ch = curl_init($_GET['url']);. – Mathias Bynens Nov 29 '09 at 13:04

+1 for being the only answer I've seen that includes the "b" for binary flag. – Will Morgan Oct 17 '12 at 16:12

Extremely elegant (requires allow_url_fopen). – Iiridayn Aug 24 '11 at 15:56
I wasnt having a go, just adding it so if any users come to this page in the future, they will see :) It is however a very elegant solution – AlexMorley-FinchMay 22 '12 at 11:59

Please ignore my comments, this function works perfectly with transparancy. I had my headers hard-coded as image/jpeg. – AlexMorley-Finch May 22 '12 at 12:10

if target folder doesn't exist, will it automatically created? – Monnster Jul 10 '15 at 15:00

@Monnster, no, it won't for normal filesystems. – Halil Özgür Jul 11 '15 at 23:43

The page is holding an animated gif image. A file is stored into the folder as flower.gif .But it is blank.No image show.any solution? – riad Apr 7 '09 at 7:07
Turn on error_reporting(E_ALL|E_STRICT) and check the return value of file_get_contents(), then you should get a reasonable error message. – soulmerge Apr 7 '09 at 7:12
Perhaps the site admin has forbidden outside referrals. In that case you can try stream_context_create() and set the appropriate HTTP headers. us2.php.net/manual/en/function.stream-context-create.php – Calvin Apr 7 '09 at 7:18
urlencode('example.com/image.php') == 'http%3A%2F%2Fexample.com%2Fimage.php', obviously not what you want. Also file is binary, proper flag needs to be set. – vartec Apr 7 '09 at 7:19

Bit of an old thread... but don't forget file permissions for the directory you are saving into. Just wasted ten minutes forgetting the obvious. – Squiggs Nov 23 '10 at 9:28

Here you go, the example saves the remote image to image.jpg.

function save_image($inPath,$outPath)
{ //Download images from remote server
    $in=    fopen($inPath, "rb");
    $out=   fopen($outPath, "wb");
    while ($chunk = fread($in,8192))
    {
        fwrite($out, $chunk, 8192);
    }
    fclose($in);
    fclose($out);
}

save_image('http://www.someimagesite.com/img.jpg','image.jpg');

The guys url is example.com/image.php. Notice that it is a php generated image an not a simple jpeg. – andrew Jan 18 '11 at 21:14

How is the generation of the image or the files extension at all relevant to the question? – Sam152 Jan 19 '11 at 10:33
fopen needs allow_url_fopen=1 too – zloctb Sep 18 '13 at 12:04

What is that '8192' magic number? – Sam Thompson Jun 11 '15 at 21:48
@SamThompson from the PHP documentation it means chunk size (usually 8192). – Daan Mar 2 '16 at 9:09

Vartec's answer with cURL didn't work for me. It did, with a slight improvement due to my specific problem.

e.g.,

When there is a redirect on the server (like when you are trying to save the facebook profile image) you will need following option set:

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

The full solution becomes:

$ch = curl_init('http://example.com/image.php');
$fp = fopen('/my/folder/flower.gif', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch);
curl_close($ch);
fclose($fp);

I wasn't able to get any of the other solutions to work, but I was able to use wget:

$tempDir = '/download/file/here';
$finalDir = '/keep/file/here';
$imageUrl = 'http://www.example.com/image.jpg';

exec("cd $tempDir && wget --quiet $imageUrl");

if (!file_exists("$tempDir/image.jpg")) {
    throw new Exception('Failed while trying to download image');
}

if (rename("$tempDir/image.jpg", "$finalDir/new-image-name.jpg") === false) {
    throw new Exception('Failed while trying to move image file from temp dir to final dir');
}

See file()^{PHP Manual}:

$url    = 'http://mixednews.ru/wp-content/uploads/2011/10/0ed9320413f3ba172471860e77b15587.jpg';
$img    = 'miki.png';
$file   = file($url);
$result = file_put_contents($img, $file)
