PHP實現遠程下載檔案到本地

代碼很簡單就不多廢話了，直接奉上：

<?phpecho 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;    }  }}?>

再來個遠程下載檔案到伺服器

<form method="post"><input name="url" size="50" /><input name="submit" type="submit" /></form>< ?php// maximum execution time in secondsset_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內容了，希望大家能夠喜歡。
