PHP捲曲從URL

Question

發佈圖像目前，上傳本地文件夾中的圖像我使用捲曲和PHP，這裏是我的代碼：

$url = 'http://myprestashop.com/api/images/products/1'; 

$image_path = 'C:\\my_image.png'; 
$key = 'My web service key'; 

$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_USERPWD, $key.':'); 
curl_setopt($ch, CURLOPT_POSTFIELDS, array('image' => '@'.$image_path)); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
$result = curl_exec($ch); 
curl_close($ch); 

我怎樣才能員額從URL（http://imageserver.com/image.jpeg）圖像，而不是本地文件夾（ C：\ my_image.png）？可能嗎？

只是改變你的圖像路徑，並嘗試這段代碼。

$url = 'http://myprestashop.com/api/images/products/1'; 

$data = array('key' => 'My web service key', 'image_path' => '@/home/user/test.png'); 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_POSTFIELDS, $data); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
$result = curl_exec($ch); 
curl_close($ch);
