file_get_contents() find why not work

Question

<?

$ip = '95.79.1.36'; //russian ip for test
$str = 'http://ipgeobase.ru:7020/geo?ip='.$ip;
$content = file_get_contents($str);
preg_match_all('#<country>(.*)(</country>)#Usi', $content, $matches); 
$country = $matches[0][0];
preg_match_all('#<city>(.*)(</city>)#Usi', $content, $matches); 
$city = $matches[0][0];
if($country == 'RU'){
echo 'City: '.$city.'';
}else{
echo 'Country: '.$country.'';
}

?>

The problem is $country == 'RU' , not work, my question is why ?

Thanks )))

probably because what you are trying to get content of is not a file on the server on which this code is running. It should be a path `/home/php/index.php` UNLESS your php is properly configured. — Félix Adriyel Gagnon-Grenier, Mar 10 '14 at 20:45
@FélixGagnon-Grenier `file_get_contents()` supports http stream wrappers and will happily retrieve a URL _if PHP is configured to permit it_ via `allow_url_fopen`. — Michael Berkowski, Mar 10 '14 at 20:46
I think he means that $country equals 'RU', but it skips the if, so this script shows "Country: RU" — , Mar 10 '14 at 20:50

Your server probably does not allow_url_fopen (php.ini directive). Anyway, the technology you are looking for for this particular case is cURL : https://php.net/curl.

I'd be delighted to provide more explanations about your code specifically, and even provide cURL code samples, once you'll have edited your question properly, with more information and attempts resulting of your efforts.

You probably shouldn't be parsing HTML/XHTML/XML with Regex. See: RegEx match open tags except XHTML self-contained tags

I recommend using PHP's SimpleXML parser. The following worked for me:

<?php
$ip = '95.79.1.36'; //russian ip for test
$str = 'http://ipgeobase.ru:7020/geo?ip='.$ip;

$results = simplexml_load_file($str);
$country = $results->ip->country;
$city = $results->ip->city;

if($country == 'RU'){
echo 'City: '.$city.'';
}else{
echo 'Country: '.$country.'';
}

?>
