too long

is it possible to retrieve $_get's index name? eg. example.php?la=1&lala=2&lalala=3

how to print 'la', 'lala' and 'lalala'?

many thanks

foreach($_GET as $key => $value)
{
  echo "index ".$key." has the value ".$value;
}

var_dump( array_keys( $_GET ) );

echo implode(', ', array_keys($_GET));

foreach(array_keys($_GET) as $key){
   echo $key;
}

use array_keys

print_r(array_keys($_GET))

or

Use a foreach loop

foreach($_GET as $key => $val)
{
   echo $key;
}

<?php
if ($_GET["la"]=="1") {
     echo "la";
}
if ($_GET["lala"]=="2") {
     echo "lala";
}
if ($_GET["lalala"]=="3") {
    echo "lalala";
}
?>
