PHP $_GET example

PHP GET sends data or a value through the URL, obviously not good or used for passwords but it is good to shape that URL’s page contents. Do note that GET is limited to 1024 characters.


$id = $_GET['id'];

function get_name($id){
$data = json_decode(file_get_contents("".$id.""),true);
$name = $data->name;
return $name;

echo get_name($id);

For the above example when we navigate to profile.php?id=56389 it will echo the name for profile 56389 from the api (example). To get the name for id 341 we just need to navigate to profile.php?id=341 and don’t need to change any code. You can see how easy $_GET can make things and this is just a small example.
