从浏览器调用 PHP cURL 下载不起作用

Question

我想要一个可以从浏览器访问的 php 脚本，该脚本会将文件下载到我的远程服务器（而不是我的计算机）。 这是我从浏览器调用的完整代码 localhost/download.php 但它不起作用（在网络管理器中我看到正在下载某些东西但在项目文件夹中我找不到它）：

<?  
    function download($url, $referer, $name)
    {
        $path = $name.'.mp3';
        $fp = fopen($path, 'w');
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_FILE, $fp);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_HEADER, false);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(
                    'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:13.5) Gecko/20100101 Firefox/13.4.9\r\n',
                    "Referer: $referer" 
        ));
        $data = curl_exec($ch);
        curl_close($ch);
        fwrite($fp, $data);
        fclose($fp);
    }

    echo 'Please wait it is downloading...<br/>';
    /*$url = $_GET['url'];
    $referer = $_GET['referer'];
    $name = $_GET['name'];*/
    $url = "http://stream.get-tune.net/file/91259796/101538464/3652118538/ee58ddeb905ffa12/Palwan_Halmyradow_-_Sensiz_(get-tune.net).mp3";
    $referer = "http://get-tune.net/?a=music&q=palwan+halmyradow";
    $name = "Palwan Halmyradow - Sensiz";
    download($url, $referer, $name);
?>

但是当我从命令行调用以下命令时它可以工作：

php /var/www/idym/download.php

有什么问题？

Answer 1

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

差异可能是由于 cli php 和 apache php 的配置不同造成的。

完整代码：

function download($url, $referer, $name)
{
    $path = $name.'.mp3';
    $fp = fopen($path, 'w');
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_FILE, $fp);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HEADER, false);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
                'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux i686; rv:13.5) Gecko/20100101 Firefox/13.4.9\r\n',
                "Referer: $referer" 
    ));
    $data = curl_exec($ch);
    curl_close($ch);
    fwrite($fp, $data);
    fclose($fp);
}
