Thanks! Is there a problem using that script if the generated xml of the URL is so huge about 50MB?

谢谢!如果生成的URL的xml如此巨大,大约50MB,是否存在使用该脚本的问题?

Here's my code please take a look tell me if it is okay.

这是我的代码,请看看是否可以。

$url = "http://projects.com/read.php";
$fp = fopen($url, 'r'); 
if ($fp) {
    while (!feof($fp))
        $buffer .= fgets($fp, 1024);
    fclose($fp);
    file_put_contents('file.xml', $buffer);
} else {
    echo 'Could not connect to: ' . htmlentities($url) . '<br />';
    echo 'Error #' . $err_num.': ' . $err_msg;
    exit;
}
