php实现远程下载文件到本地,
代码很简单就不多废话了,直接奉上:
<?php
echo httpcopy("http://www.baidu.com/img/baidu_sylogo1.gif");
function httpcopy($url, $file="", $timeout=60) {
$file = empty($file) ? pathinfo($url,PATHINFO_BASENAME) : $file;
$dir = pathinfo($file,PATHINFO_DIRNAME);
!is_dir($dir) && @mkdir($dir,0755,true);
$url = str_replace(" ","%20",$url);
if(function_exists('curl_init')) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$temp = curl_exec($ch);
if(@file_put_contents($file, $temp) && !curl_error($ch)) {
return $file;
} else {
return false;
}
} else {
$opts = array(
"http"=>array(
"method"=>"GET",
"header"=>"",
"timeout"=>$timeout)
);
$context = stream_context_create($opts);
if(@copy($url, $file, $context)) {
//$http_response_header
return $file;
} else {
return false;
}
}
}
?>
再来个远程下载文件到服务器
1.) 将所有文件解压到php环境中,本程序才用smarty+php+mysql设计。如果运行不了,请修改hhy文件夹下的smarty.php文件改法请看说明2.) 修改configs下的config.inc.php下的连接数据库的密码和用户名3.) 本程序没有做安全页面,人工导入sql.inc到mysql数据库。管理员初始化帐号为admin,密码为hhy。后台地址:http://你的网站地址/h
< ?php // maximum execution time in seconds set_time_limit (24 * 60 * 60); if (!isset($_POST['submit'])) die(); // folder to save downloaded files to. must end with slash $destination_folder = 'temp/'; $url = $_POST['url']; $newfname = $destination_folder . basename($url); $file = fopen ($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); } ?>
以上所述就是本文的全部内容了,希望大家能够喜欢。
