1、fsockopen方法。

以下为引用的内容：

php

$url = “//www.example.net/xxx/xxx.jpg”;

$t = parse_url($url);

$host = $t['host'];

$file = $t['path'];

$fp = fsockopen($host,80, $errno, $errstr, 30);

if($fp)

{

$header = “GET $file HTTP/1.1/r/n”;

$header .= “Host: $host/r/n”;

$header .= “User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; zh-CN; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1/r/n”;

$header .= “Referer: //$host/r/n”;

$header .= “Connection: Close/r/n/r/n”;

fwrite($fp, $header);

$jpg = fopen($path . basename($file), “wb”);

while (!feof($fp))

{

$s = fgets($fp,128);

fwrite($jpg,$s);

}

fclose($jpg);

fclose($fp);

}

?>

2.curl方法。需要php中启用curl。

以下为引用的内容：

php

set_time_limit(0);

ini_set(’display_errors’,true);//Just in case we get some errors, let us know….

$host = “www.example.net”;

$urls=array(

“//$host/xxx/xxx.jpg”,

“//$host/xxx/yyy.jpg”

);

$save_to=’./’;

$mh = curl_multi_init();

foreach ($urls as $i => $url)

{

$g=$save_to.basename($url);

if(!is_file($g))

{

$conn[$i]=curl_init($url);

$fp[$i]=fopen ($g, “wb”);

curl_set($conn[$i], CURLOPT_USERAGENT, “Mozilla/5.0 (Windows; U; Windows NT 6.0; zh-CN; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1″);

curl_set($conn[$i], CURLOPT_REFERER, “//$host”);

curl_set($conn[$i], CURLOPT_FILE, $fp[$i]);

curl_set($conn[$i], CURLOPT_HEADER ,0);

curl_set($conn[$i], CURLOPT_CONNECTTIMEOUT,600);

curl_set($conn[$i], CURLOPT_FOLLOWLOCATION, 1);

//curl_set($conn[$i], CURLOPT_RETURNTRANSFER, 0);

//curl_set($conn[$i], CURLOPT_VERBOSE, 0);

curl_multi_add_handle ($mh,$conn[$i]);

}

}

do {

$n=curl_multi_exec($mh,$active);

}

while ($active); php程序员站

foreach ($urls as $i => $url)

{

curl_multi_remove_handle($mh,$conn[$i]);

curl_close($conn[$i]);

fclose ($fp[$i]);

}

curl_multi_close($mh);

?>
