How can PHP be used to format dates entered through a calendar tool to ensure consistency and accuracy in date comparisons?

When dates are entered through a calendar tool, they may be in different formats which can lead to inconsistencies in date comparisons. To ensure consistency and accuracy, you can use PHP's `strtotime()` function to convert the entered dates into a standardized format before performing any comparisons. 

// Example code to format dates entered through a calendar tool
$entered_date = "12/31/2022"; // Date entered through the calendar tool

// Convert the entered date to a standardized format (YYYY-MM-DD)
$standardized_date = date("Y-m-d", strtotime($entered_date));

// Now you can use $standardized_date for date comparisons
echo $standardized_date; // Output: 2022-12-31
