hey guys, i think i lost my mind.
print_r($location); lists some geodata.
array (
'geoplugin_city' => 'My City',
'geoplugin_region' => 'My Region',
'geoplugin_areaCode' => '0',
'geoplugin_dmaCode' => '0',
'geoplugin_countryCode' => 'XY',
'geopl ...
when I iterate through it with a foreach loop I can print each line. However shouldn't it be possible to just get a specific value out of the array?
like print $location[g4]; should print the countryCode shouldn't it? Thank you!
echo $location['geoplugin_countryCode'];
Yes, you can get a specific value by key. The keys in your case are the geoplugin_ strings.
To get the country code:
// XY
$location['geoplugin_countryCode'];
$location['geoplugin_countryCode'];
would access country code
Where does "g4" come from? Did you mean "4"?
If you had a normal numerically-indexed array then, yes, you could write $location[4]. However, you have an associative array, so write $location['geoplugin_countryCode'].
there you are using an associative array, it is an array with a user defined key:value pair (similar to dictionaries on Python and Hash Tables on C#)
You can access the elements just using the Key (in this case geoplugin_city or geoplugin_region)
Using the standard array syntax:
$arrayValue = $array[key]; //read
$array[key] = $newArrayValue; //write
For example:
$location['geoplugin_city']; or $location['geoplugin_region'];
If you are not familiarwith PHP arrays you can take a look here:
