You can use:
您可以使用：
<?php
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://www.example.com/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
$out = curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
$fp = fopen('data.txt', 'w');
fwrite($fp, $out);
fclose($fp);
?>

I think curl has -o option to write the output to a file instead of stdout.
我认为 curl 有 -o 选项可以将输出写入文件而不是标准输出。
After -o you have to provide the name of the output file.
在 -o 之后，您必须提供输出文件的名称。
example:
例子：
curl -o path_to_the_file url
