How can PHP developers optimize their code to efficiently display content based on specific date ranges without the need for manual adjustments or yearly updates?

One way PHP developers can optimize their code to efficiently display content based on specific date ranges without the need for manual adjustments or yearly updates is by using PHP's date functions to dynamically determine the start and end dates of the desired range. By calculating the start and end dates based on the current date, the code can automatically adjust to display the relevant content without requiring manual updates.

// Get the current date
$currentDate = date('Y-m-d');

// Calculate the start date of the desired range (e.g., 30 days before the current date)
$startDate = date('Y-m-d', strtotime($currentDate . ' - 30 days'));

// Calculate the end date of the desired range (e.g., the current date)
$endDate = $currentDate;

// Use $startDate and $endDate to fetch and display content within the specified date range
$query = "SELECT * FROM content WHERE post_date BETWEEN '$startDate' AND '$endDate'";
// Execute the query and display the content
