PHP Practical Instance capture Remote Web site picture Save to Local

PHP Practical Instance capture Remote Web site picture Save to Local
First from the article to all the with the right to dig out. $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]);

Copy code Step two. Loop the $img_array array. Do picture save and post position replace foreach ($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//The following function and class are 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
