Question

我正在寻找一种明确的方式来检测访客是否来自中东。如果是的话，我需要显示一个不同的标题图像（当前的标题图像中有一个标题，所以它是不受欢迎的。）

我可以编写if then else，但我只是想找一个简单的函数来检测。以下是我用IP获取国家的功能：

function get_country_by_ip($ip){

    if(!$ip) return false;    # Missing parameter

    # Pull the XML
    $url = 'http://api.hostip.info/?ip='.$ip;
    $xml = simplexml_load_file($url);

    # Parse the data and store into array
    $citystate = explode(", ", $xml->children('gml', true)->featureMember->children()->Hostip->children('gml', true)->name);
    $result['city'] = $citystate[0];
    $result['state'] = $citystate[1];
    $result['country'] = $xml->children('gml', true)->featureMember->children()->Hostip->countryName;
    $result['country_abbr'] = $xml->children('gml', true)->featureMember->children()->Hostip->countryAbbrev;

    return (object) $result;

}

有人可以帮忙吗？感谢。

Answer 1

您可以定义哪些国家属于“中东”组 - 通过直接在PHP文件或数据库中定义可配置数组，然后检查您的函数返回的给定国家/地区是否属于“属于”的国家/地区列表中东”。通过你的例子，像这样：

$middleEast = array(
 'Syria',
 'Iraq',
 ... // all the rest
);

$country = get_country_by_ip($ip);

if (in_array($country['country'], $middleEast) {
 echo 'Middle East!';
 exit;
}

<?php

/* get country by ip */

function get_country_by_ip($ip){

    if(!$ip) return false;

    /* pull the xml */

    $url = 'http://api.hostip.info/?ip='.$ip;
    $xml = simplexml_load_file($url);


    /* parse the data and store into array */

    $citystate = explode(", ", $xml->children('gml', true)->featureMember->children()->Hostip->children('gml', true)->name);

    $result['city'] = $citystate[0];
    $result['state'] = $citystate[1];

    $result['country'] = (array) $xml->children('gml', true)->featureMember->children()->Hostip->countryName;
    $result['country'] = $result['country'][0];

    $result['country_abbr'] = (array) $xml->children('gml', true)->featureMember->children()->Hostip->countryAbbrev;
    $result['country_abbr'] = $result['country_abbr'][0];

    return (object) $result;

}


/* get country */

$geo_info = get_country_by_ip($_SERVER['REMOTE_ADDR']);


/* MENA countries */

$mena = array(

    'ALGERIA',

    'BAHRAIN',

    'EGYPT',

    'IRAN',

    'IRAQ',

    'ISRAEL',

    'JORDAN',

    'KUWAIT',

    'LEBANON',

    'LIBYA',

    'MOROCCO',

    'OMAN',

    'PALESTINE',

    'QATAR',

    'SAUDI ARABIA',

    'SYRIA',

    'TUNISIA',

    'UNITED ARAB EMIRATES',

    'YEMEN',

    'ARMENIA',

    'AZERBAIJAN',

    'CYPRUS',

    'DJIBOUTI',

    'MALTA',

    'MAURITANIA',

    'SAHRAWI ARAB DEMOCRATIC REPUBLIC',

    'SOMALIA',

    'SUDAN',

    'TURKEY',

);


/* image with a hog */

$img = 'mmm-pork.jpg';

if(in_array($geo_info->country, $mena)){


    /* image with no hog */

    $img = 'cant-have-pork.jpg';

} ?>
