我需要使用CURL從URL保存圖像并將其保存到服務(wù)器上的文件夾中。我一直在努力與此代碼無濟(jì)于事。理想情況下，我想獲取圖像并將其另存為“ photo1”或其他內(nèi)容。救命！ function GetImageFromUrl($link) { $ch = curl_init(); curl_setopt($ch, CURLOPT_POST, 0); curl_setopt($ch,CURLOPT_URL,$link); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $result=curl_exec($ch); curl_close($ch); return $result; } $sourcecode = GetImageFromUrl($iticon); $savefile = fopen(' /img/uploads/' . $iconfilename, 'w'); fwrite($savefile, $sourcecode); fclose($savefile);

嘗試這個：
function grab_image($url,$saveto){
$ch = curl_init ($url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
$raw=curl_exec($ch);
curl_close ($ch);
if(file_exists($saveto)){
unlink($saveto);
}
$fp = fopen($saveto,'x');
fwrite($fp, $raw);
fclose($fp);
}
并確保在php.ini中啟用allow_url_fopen

Komang答案的改進(jìn)版本（添加引薦來源和用戶代理，檢查是否可以寫入文件），如果可以，則返回true，如果有錯誤，則返回false：
public function downloadImage($url,$filename){
if(file_exists($filename)){
@unlink($filename);
}
$fp = fopen($filename,'w');
if($fp){
$ch = curl_init ($url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, 1);
$result = parse_url($url);
curl_setopt($ch, CURLOPT_REFERER, $result['scheme'].'://'.$result['host']);
curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (Windows NT 10.0; WOW64; rv:45.0) Gecko/20100101 Firefox/45.0');
$raw=curl_exec($ch);
curl_close ($ch);
if($raw){
fwrite($fp, $raw);
}
fclose($fp);
if(!$raw){
@unlink($filename);
return false;
}
return true;
}
return false;
}
