Is it recommended to use variable variables in PHP for date calculations?

Using variable variables in PHP for date calculations is not recommended as it can lead to confusion and make the code harder to read and maintain. It is better to use regular variables or arrays to store and manipulate dates in PHP. 

// Incorrect usage of variable variables for date calculations
$day = 1;
$month = 9;
$year = 2021;

$variableName = 'day';
$$variableName = $$variableName + 1;

echo "$day/$month/$year"; // Output: 2/9/2021

// Correct way to store and manipulate dates using regular variables
$day = 1;
$month = 9;
$year = 2021;

$day = $day + 1;

echo "$day/$month/$year"; // Output: 2/9/2021
