PHP Save remote picture, the following code is my own writing, but there is a problem is placed on the server to save the picture success is not very high, I use is file_get_contents to obtain, finally found if the host has anti-theft of the study took, we deceive the host method to do, is to use Fsockopen to send a user package 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 Fsockopen's 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, $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, $errno, $errstr, ten) or Die ($ghost. '
');
Fwrite ($m _fp, $sessionQuery);
$lnum = 0;
Get detailed answer Header
$gcookie = "";
while (!feof ($m _fp)) {
$line = Trim (fgets ($m _fp,256));
if ($line = = "" | | $lnum >100) break;
else{
if (eregi ("^cookie", $line)) {
$gcookie = $line;
Break
}
}
}
Fclose ($m _fp);
}
Ha such words will be able to save the remote have pictures of anti-theft host pictures.
