php实现远程网络文件下载到服务器指定目录(方法二)

<?php
// maximum execution time in seconds
set_time_limit (24 * 60 * 60);
//if (!isset($_POST['submit'])) die();
// folder to save downloaded files to. must end with slash
$destination_folder = 'down/';

//$url = $_POST['url'];
$url="http://192.168.31.1/".urlencode(iconv("GB2312","UTF-8","测试.doc"));  //英文名字直接写路径就可以了
echo $url."<br>";
$newfname = $destination_folder . iconv("UTF-8","GB2312",urldecode(basename($url)));
echo $newfname;
//exit;
$file = fopen ($url, "rb");
if ($file) {
$newf = fopen ($newfname, "wb");
if ($newf)
while(!feof($file)) {
fwrite($newf, fread($file, 1024 * 8 ), 1024 * 8 );
}
}
if ($file) {
fclose($file);
}
if ($newf) {
fclose($newf);
}
?>
