PHP- file_get_contents failed to open stream: Connection refused

Question

I am using the following API for getting the country code using IP

http://api.hostip.info/country.php?ip=' . $IP

Example: on Localhost

$IP = '202.71.158.30';

//pass the ip as a parameter for follow URL it will return the country

$country_code = file_get_contents('http://api.hostip.info/country.php?ip=' . $IP);

and its working fine here and showing the country code.

But it showing error on Server

Example:

$IP=$_SERVER['REMOTE_ADDR'];

$country_code = file_get_contents('http://api.hostip.info/country.php?ip=' . $IP);

Showing following error:

Warning: file_get_contents(http://api.hostip.info/country.php?ip=101.63.xx.xxx) [function.file-get-contents]: failed to open stream: Connection refused in /srv/disk4/1322145/www/servername.in/app/header.php on line 12

Whats wrong with this?

Probably this has little to do with PHP and more with network restrictions. Try dumping $http_response_header after file_get_contents to get more info about why it failed. — marekful

Make sure that you can open a url with fopen. See: php.net/… — Robert K

@MarcellFülöp : But its working on localhost only the error showing on server. So is it the issue of $_SERVER['REMOTE_ADDR']; ? — J.K.A.

@MarcellFülöp : var_dump($country_code); showing bool(false) — J.K.A.

I meant $http_response_header. This variable gets populated by PHP when file_get_contents is used with the HTTP wrapper and might give useful information about the HTTP request. — marekful

You can use CURL in place of file_get_contents()

<?php
    $IP = '202.71.158.30'; 
    $runfile = 'http://api.hostip.info/country.php?ip=' . $IP;

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $runfile);

    curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);

    $content = curl_exec ($ch);

    curl_close ($ch); 

    echo $content;

Use curl method instead of file_get_contents()

It does not work on localhost at google.com. Instead use other engine or use curl below:

Make a function or use inside the same function:

I prefer it to use in a function to avoid repetition in future.

$IP = '202.71.158.30';
$country_code = file_get_contents_fun('http://api.hostip.info/country.php? 
ip='.$IP);
public function file_get_contents_fun($url){
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_TIMEOUT,30);
    $content = curl_exec ($ch);
    curl_close ($ch); 
    return $content;
}

Some servers do not permit accessing through IP address in your request. You can use CURL to prevent this problem.

In my case the Fail2Ban extension in Plesk suddenly started IP-blocking the server that did the file_get_contents() requests. This is probably not going to be the issue, but I just wanted you to be aware of such a possibility.

Spent the past 5 hours fighting with this thing. This helped me. My server was banning itself on postfix! and it was killing the file_get_contents() response.

OMG!!!! I just spent a whole day trying to fix this. Your comment fixed it! Thank You. Saved me so much work. I thought I would have to re-code using cURL. Was working for 12 months then all of a sudden stopped. Fail2Ban was the culprit. Locked out the host server. Thank You again.

add optional parameter in file_get_contents using stream_context_create function to open stream connection valid.

$context = stream_context_create([
    'http' => ['protocol_version' => '1.1'],
]);

$result = file_get_contents($url, false, $context);
var_dump($result);
