file_get_contents / curl PHP函数不适用于IP地址

Question

My server contain a file at http://XX.XX.XX.XX:7550/check.txt and in which only Online is written. Now I am on my shared hosting and I want to get Online in my shared hosting php file for that I am using the below code in my shared hosting php file.

<?php
var_export(ini_get('allow_url_fopen'));
$uri = 'http://XX.XX.XX.XX:7550/check.txt';
$result = file_get_contents($uri);
echo $result;
?> 

But I am only getting '1' instead of '1' Online . So can you answer my why not working when I enter my server IP?

Note: And when I am adding http://www.google.com instead of http://XX.XX.XX.XX:7550/check.txt then I am getting whole Google page.

Important Note: I am able to open http://XX.XX.XX.XX:7550/check.txt in my web-browser directly via proxy means no firewall blocking is in my server ( Ubuntu Server 14.04 LTS ).

UPDATE:

I also tried CURL and that's also not working with http://XX.XX.XX.XX:7550/check.txt but working with http://www.google.com .

<?php
function curl_load($url){
    curl_setopt($ch=curl_init(), CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $response = curl_exec($ch);
    curl_close($ch);
    return $response;
}
$url = "http://XX.XX.XX.XX:7550/check.txt";
echo curl_load($url);
?>

尝试使用cUrl而不是file_get_contents。
