php怎么调用远程数据？实现代码

$str = file_get_contents("https://www.mycodes.net");
if ($str !== false) {
// do something with the content
echo $str;
}
?>

$ch = curl_init("https://www.mycodes.net/");
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$str = curl_exec($ch);
if ($str !== false) {
// do something with the content
echo $str;
}
curl_close($ch);
?>
