变量说明:$url 是远程图片的完整url地址,不能为空,$filename 是可选变量,如果为空,本地文件名将基于时间和日期. 
自动生成,代码如下:
function grabimage($url,$filename="") {  
  if($url==""):return false;endif; 
  if($filename=="") {  
    $ext=strrchr($url,".");  
    if($ext!=".gif" && $ext!=".jpg"):return false;endif;  
    $filename=date("dmyhis").$ext;  
  } 
  ob_start();  
  readfile($url);  
  $img = ob_get_contents();  
  ob_end_clean(); //开源代码phpfensi.com 
  $size = strlen($img); 
  $fp2=@fopen($filename, "a");  
  fwrite($fp2,$img);  
  fclose($fp2); 
  return $filename;  
} 
如果可用采集防采集的功能把fopen改成如下:
$ch = curl_init(); 
curl_setopt($ch, curlopt_url, $url);//这是目标地址 
curl_setopt($ch, curlopt_header, 0); 
curl_setopt($ch, curlopt_returntransfer, 1); 
curl_setopt($ch, curlopt_referer,   $referer);//这里伪造 
$data = curl_exec($ch); 
curl_close($ch); 
echo $data;
