php使用curl或fsockopen下载远程图片_中博软件学院

1、fsockopen方法。
以下为引用的内容：
php
$url = “http://www.example.net/xxx/xxx.jpg”;
$t=pars{e}_{u}rl($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”;
$header.=“Referer:http://$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”;
$urls=array(“http://$host/xxx/xxx.jpg”,
“http://$host/xxx/yyy.jpg”
);
$save_to=’./’;
$mh=cur{l}_{m}ult{i}_{i}nit();foreach($urls as $i => $url)
{
$g=$save_to.basename($url);if(!i{s}_{f}ile($g))
{
$conn[$i]=curl_init($url);
$fp[$i]=fopen ($g,“wb”);cur{l}_{s}et($conn[$i],CURLOP{T}_{U}SERAGENT,“Mozilla/5.0(Windows;U;WindowsNT6.0;zh-CN;rv:1.9.0.1)Gecko/2008070208Firefox/3.0.1″);cur{l}_{s}et($conn[$i],CURLOP{T}_{R}EFERER,“http://$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 {
$n=cur{l}_{m}ult{i}_{e}xec($mh,KaTeX parse error: Expected 'EOF', got '}' at position 10: active); }̲ while (active); php程序员站
foreach ($urls as $i => KaTeX parse error: Expected '}', got 'EOF' at end of input: …_remove_handle(mh,$conn[$i]);
curl_close($conn[$i]);
fclose ($fp[$i]);
}
curl_multi_close($mh);
?>
