Saving image from PHP URL

Use PHP's function copy():

copy('http://example.com/image.php', 'local/folder/flower.jpg');

Note: this requires allow_url_fopen

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

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);
