How can you extract and sort values from a multidimensional array in PHP?

To extract and sort values from a multidimensional array in PHP, you can use a combination of array_column() to extract values and array_multisort() to sort the extracted values. 

// Sample multidimensional array
$multiArray = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Jane', 'age' => 25],
    ['name' => 'Alice', 'age' => 35]
];

// Extract 'age' values from the multidimensional array
$ages = array_column($multiArray, 'age');

// Sort the extracted 'age' values
array_multisort($ages, SORT_ASC, $multiArray);

// Output the sorted multidimensional array
print_r($multiArray);
