How can one reference a value from one array to another value within the same array in PHP?

To reference a value from one array to another value within the same array in PHP, you can simply assign the value of one array element to another array element. This can be done by accessing the specific key of the first array and assigning it to the key of the second array. Example: 

<?php
// Create an array
$array = array(
    'key1' => 'value1',
    'key2' => 'value2'
);

// Reference value from one array to another within the same array
$array['key2'] = $array['key1'];

// Display the modified array
print_r($array);
?>
