What are some common pitfalls to avoid when trying to display the last update date in PHP?

One common pitfall when displaying the last update date in PHP is not updating the date when the content is changed. To avoid this, you can store the last update date in a database or a separate file and update it whenever the content is modified. Another pitfall is not handling timezones properly, which can lead to incorrect date displays. To address this, you can use PHP's date_default_timezone_set function to set the timezone before displaying the date. 

// Store the last update date in a variable or retrieve it from a database
$lastUpdateDate = "2022-01-01";

// Update the last update date whenever the content is modified
// For example, after updating content in a database
$lastUpdateDate = date("Y-m-d");

// Set the timezone to display the date correctly
date_default_timezone_set('America/New_York');

// Display the last update date
echo "Last updated on: " . date("F j, Y", strtotime($lastUpdateDate));
