How can PHP developers efficiently troubleshoot and debug date sorting issues in their code?

To efficiently troubleshoot and debug date sorting issues in PHP code, developers can ensure that dates are properly formatted and converted to a consistent format before sorting. They can also use built-in PHP functions like strtotime() to convert date strings to timestamps for accurate sorting. Additionally, developers can use var_dump() or print_r() to inspect the dates being sorted and identify any discrepancies. 

// Sample code snippet to sort an array of dates in ascending order
$dates = ['2022-01-15', '2021-12-20', '2022-02-10'];

// Convert date strings to timestamps for accurate sorting
foreach ($dates as $key => $date) {
    $dates[$key] = strtotime($date);
}

// Sort the dates in ascending order
asort($dates);

// Output the sorted dates
foreach ($dates as $date) {
    echo date('Y-m-d', $date) . "\n";
}
