php to save remote images. The following code was written by myself, but one problem is that the success of saving images when placed on the server is not very high. I used file_get_contents to obtain it, and finally found that if If the host is anti-theft, it will be read. The way we deceive the host is to use fsockopen to send a user packet to the host

function get_remote($body){
set_time_limit(0);
$img_array = array();
$img_path = "get_pic/";
preg_match_all("/(src|SRC)=["|'| ]{0,}(http://(.*).(gif|jpg|jpeg|png))/isU",$body,$img_array) ;
$img_array = array_unique($img_array[2]);
foreach ($img_array as $key => $value) {
$get_file = @file_get_contents($value);
$filetime = time();
!is_dir($img_path) ? mkdir($img_path) : null;
$filename = date("YmdHis",$filetime).rand(1,999).'.'.substr($value,-3,3);
if(empty($get_file)){
sleep(3);
$get_file = @file_get_contents($value);
If(empty($get_file)){
$body = preg_replace("/".addcslashes($value,"/")."/isU", 'http://www.111cn.cn/notfound.jpg', $body);
Continue;
}
}
if(!empty($get_file) ){
$fp = fopen($img_path.$filename,"w");
If(fwrite($fp,$get_file)){                                        $body = preg_replace("/".addcslashes($value,"/")."/isU", $img_path.$filename, $body);
}
}
fclose($fp);
sleep(1);
}

//$body =str_replace(' //$body =str_replace(' return $body;

}

Let’s take a look at the fsockopen method.

if($gcookie=="" && !empty($rfurl)) $gcookie = RefurlCookie($rfurl);

$sessionQuery = "GET $gquery HTTP/1.1rn";
$sessionQuery .= "Host: $ghostrn";
$sessionQuery .= "Referer: $rfurlrn";
$sessionQuery .= "Accept: */*rn";
$sessionQuery .= "User-Agent: Mozilla/4.0 (compatible; MSIE 5.00; Windows 98)rn";
if($gcookie!=""&&!ereg("[rn]",$gcookie)) $sessionQuery .= $gcookie."rn";
$sessionQuery .= "Connection: Keep-Alivernrn";
$errno = "";
$errstr = "";
$url ='http://www.moko.cc';
$m_fp = fsockopen($url,80,$errno,$errstr,10);
fwrite($m_fp,$sessionQuery);

function RefurlCookie($gurl){
 global $gcookie,$lastRfurl;
 $gurl = trim($gurl);
 if(!empty($gcookie) && $lastRfurl==$gurl) return $gcookie;
 else $lastRfurl=$gurl;
 if(trim($gurl)=='') return '';
 $urlinfos = GetHostInfo($gurl);
  $ghost = $urlinfos['host'];
  $gquery = $urlinfos['query'];
  $sessionQuery = "GET $gquery HTTP/1.1rn";
  $sessionQuery .= "Host: $ghostrn";
  $sessionQuery .= "Accept: */*rn";
  $sessionQuery .= "User-Agent: Mozilla/4.0 (compatible; MSIE 5.00; Windows 98)rn";
  $sessionQuery .= "Connection: Closernrn";
  $errno = "";
  $errstr = "";
  $m_fp = fsockopen($ghost, 80, $errno, $errstr,10) or die($ghost.'
');
  fwrite($m_fp,$sessionQuery);
  $lnum = 0;
  //获取详细应答头
  $gcookie = "";
 while(!feof($m_fp)){
   $line = trim(fgets($m_fp,256));
   if($line == "" || $lnum>100) break;
   else{
    if(eregi("^cookie",$line)){
     $gcookie = $line;
     break;
    }
   }
  }
   fclose($m_fp);
   }
  哈这样的话就可以保存远程有图片防盗的主机的图片了喽.
