What potential issues can arise with PHP code when transitioning to a new year, as seen in the forum thread?

One potential issue that can arise with PHP code when transitioning to a new year is related to date calculations. If the code relies on hard-coded dates or assumes a specific year, it may produce incorrect results or errors when the year changes. To solve this issue, it is recommended to use PHP's date functions to dynamically calculate dates based on the current year. 

// Incorrect way of calculating next year
$nextYear = date('Y') + 1;

// Correct way of calculating next year
$nextYear = date('Y', strtotime('+1 year'));
