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：
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

< ?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);
}
?>
