The remote picture in the PHP article captures the local code _php instance

First step. First from the article to all the with the right to dig out.

Copy Code code as follows:

$message//article content
Regular (this is not yet)
$reg = "/]*src=\" (http:\/\/(. +) \/(. +) \. ( JPG|GIF|BMP|BNP)) \ "/isu";
Store the IMG address in the $img _array variable
Preg_match_all ($reg, $message, $img _array, Preg_pattern_order);
Filter for duplicate pictures
$img _array = Array_unique ($img _array[1]);

Step two. Loop the $img_array array. Do picture save and post position replacement

Copy Code code as follows:

foreach ($img _array as $img) {
Judge whether it's a picture on your own website
if (' xxx.com '!= get_domain ($img)) {//If this picture is not on your own server
Reading picture files
$Gimg = new GetImage ();
$Gimg->source = $img;
$Gimg->save_to = './data/temp/';
$FILE = $Gimg->download (); Picture moved to Local
Save to Photo album get picture saved location
$img _path = pic_save ($FILE, 0, "");
Text path substitution
$message = Str_replace ($img, $img _path, $message);
}
}

.... At this time $message already the picture has been replaced with its own server local address, and the picture is also saved to its own server.

Copy Code code as follows:

One of the following functions and classes is found on the network.
Get the domain name from the URL
function Get_domain ($url) {
$pattern = "/[\w-]+\." (COM|NET|ORG|GOV|CC|BIZ|INFO|CN) (\. (CN|HK)) */";
Preg_match ($pattern, $url, $matches);
if (count ($matches) > 0) {
return $matches [0];
}else{
$rs = Parse_url ($url);
$main _url = $rs ["Host"];
if (!strcmp (Long2ip (sprintf ("%u", Ip2long ($main _url)), $main _url)) {
return $main _url;
}else{
$arr = Explode (".", $main _url);
$count =count ($arr);
$ENDARR = Array ("com", "net", "org", "3322");//com.cn net.cn, etc.
if (In_array ($arr [$count-2], $ENDARR)) {
$domain = $arr [$count-3]. "." $arr [$count-2]. ".". $arr [$count-1];
}else{
$domain = $arr [$count-2]. "." $arr [$count-1];
}
return $domain;
}//End If (!strcmp ...)
}//End If (count ...)
}//End Function
