php if else condition not working

Question

$user_ip = getenv('REMOTE_ADDR');

$geo = unserialize(file_get_contents("http://www.geoplugin.net/php.gp?ip=$user_ip"));

$city = $geo["geoplugin_city"];

$region = $geo["geoplugin_regionName"];

$country = $geo["geoplugin_countryName"];

$continent = $geo["geoplugin_continentCode"];

$continent1 = $continent;

echo "IP: " .$user_ip. "<br>";

echo "City: " .$city. "<br>";

echo "Region: " .$region. "<br>";

echo "Country: " .$country. "<br>";

echo "Continent: " .$continent1. "<br>";

This code is for getting the IP and location details.

Here, my problem is, I am getting continents as AS, EU, NA, SA

I need to change AS to Asia, EU to Europe, NA to North America and SA to South America. How to use an if else condition for this?

Of course it's not working, there is no if/else statement in your code... — Bv202

you need to use switch case for this php.net/manual/en/control-structures.switch.php — Disha V.

Don't use if/else; use a lookup array (and an if just in case if your array is not exhaustive). — Amadan

Try this -

switch ($continent1) {
    case "AS":
        $continent1 = 'Asia';
        break;
    case "EU":
        $continent1 = 'Europe';
        break;
    case "NA":
        $continent1 = 'North America';
        break;
    default:
        $continent1 = '';
}

failing having this in a DB, you could try this:

$arr_continent = array('AS'=>'Asia','EU'=>'Europe','NA'=>'North America','SA'=>'South America');
echo "Continent: " .$arr_continent[$continent1]. "<br />";

it's a lot neater than a switch statement! ;)

switch ($continent)
{
    case "AS":
        $continent1 = 'Asia';
        break;
    case "EU":
        $continent1 = 'Europe';
        break;
    case "NA":
        $continent1 = 'North America';
        break;
    // rest of codes
}

You can create a function without any use of if/else or switch statement

<?php 
   function get_continent($continent_name){
      $arr = array(
        "AS" => 'Asia',
        "EU" => 'Europe',
        "NA" => 'North America',
        "SA" => 'South America'
        // and define more keys and value pair of continent short and full name
        );

      return ($arr[$continent_name]!="") ? $arr[$continent_name] : "N/A" ;
   }

   echo get_continent("EU");

   // output - Europe
   ?>

This code will also increase reuse-ability if you need similar task to be performed again and again

You can use the switch method on your $continent1 variable to replace the values with what you want

switch($continent1)
{
    case 'AS':
       echo "Continent: Asia";
      break;
    case 'EU':
       echo "Continent: Europe";
       break;
    case 'NA':
       echo "Continent: North America";
       break;
    case 'SA':
       echo "South America";
       break;
    default:
       echo "nothing matched"
      break;
}
