javascript代码中的$ _GET ['user'] php变量[关闭]

Here is my javascript code

<script type="text/javascript">
var country,url;
country = geoip_country_code()
if(country=="US"){
    url="http://www.site.org/index.php?user=php variable";
}
setTimeout("location.href = url;",5000);
</script>

i need put $_GET['user'] php variable for get username in the current url

tried with this but not work

if(country=="US"){
    url="http://www.site.org/index.php?user=<?php echo $_GET['user']; ?>";
}

You can do this in plain javascript:

var query = (function() {
    var result = {}, keyValuePairs = location.search.slice(1).split('&');

    keyValuePairs.forEach(function(keyValuePair) {
        keyValuePair = keyValuePair.split('=');
        result[keyValuePair[0]] = keyValuePair[1] || '';
    });

    return result;
})();

if(country=="US"){
    url="http://www.site.org/index.php" + (query.user !== undefined) ? "?user=" + query.user : "";
}

See https://stackoverflow.com/a/647272/838733 for the iffy specifics.

Assuming $_GET['user'] is set:

var user = "<?php echo $_GET['user']; ?>";
url="http://www.site.org/index.php?user="+user;

This is the version using pure PHP:

$xml = simplexml_load_file("http://www.geoplugin.net/xml.gp?ip=$_SERVER['HTTP_CLIENT_IP']";
$country = geoplugin_countryCode;
if($country=="US"){ 
    $url="http://www.site.org/index.php?user=$_GET['user']"; 
}
sleep(5);
header("Location: $url");
