What are multidimensional associative arrays in PHP? How to retrieve values from them?

Multidimensional arrays store multiple arrays whereas associative arrays store key-value pairs as data. Grouped relation between data can be stored in multidimensional associative arrays.

<?php
$my_arr = array();
$my_arr['Employee'] = array(
   "Name" => "Joe",
   "Age" => "20",
   "Birth_date" => "2000",
   "Job_details" => array(
      "Position" => "Manager",
      "Salary" => "Lakhs"
   )
);
print_r($my_arr['Employee']['Name']);
echo "
";
echo $my_arr['Employee']['Age'];
?>

An array is defined that contains various attributes of an employee. The employee array is accessed based on the index names and the data is displayed on the console.
