Create associative array:

$user = [
  "name" => 'Spike',
  "surname" => 'Johnson',
  "age" => 23
];

Show the element of the array:

echo $user['name'];//Spike

Multilevel array

Example:

$families = [["Tom", "Alice"], ["Bob", "Kate"]];
echo $families[0][0];  //Tom
echo $families[0][1];  //Alice
echo $families[1][0];  //Bob
echo $families[1][1];   //Kate

If you want to output an element of a multilevel Associative array, use:

echo $families[2]['name'];//turn to the second array and look for the element with the key "name";
