The code is:

    print 'start<br>';
    $f = file_get_contents("countryinfo.xml");
    preg_match_all("/<countryCode>.*<\/countryCode>/i",$f,$str);
    preg_match_all("/<countryName>.*<\/countryName>/i",$f,$str1);
    $country_names = array();
    for ($i=0;$i<15;$i++){
      $country_names[strtolower($str[0][$i])] = $str1[0][$i];
    }
    print 'Array $country_names is:<br>';
    print_r($country_names);
    print '<br>Print command is:<br>';
    print '"AD ->".$country_names["ad"]<br>';
    print 'Error is:<br>';
    print 'AD ->'.$country_names['ad'];
