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

<form method="post">
<input name="url" size="50" />
<input name="submit" type="submit" />
</form>
< ?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);
}
?>
