How can one effectively handle and extract the first value from a multidimensional array in PHP?

To extract the first value from a multidimensional array in PHP, you can use array_values() to get all the values of the first level of the array and then access the first element of that resulting array.

// Sample multidimensional array
$multiArray = array(
    array(1, 2, 3),
    array(4, 5, 6),
    array(7, 8, 9)
);

// Extract the first value from the multidimensional array
$firstValue = array_values($multiArray)[0][0];

echo $firstValue; // Output: 1
