How can PHP be used to calculate the difference in days between a date from a database and the current date?

To calculate the difference in days between a date from a database and the current date in PHP, you can retrieve the date from the database, convert it to a Unix timestamp, get the current date as a Unix timestamp, calculate the difference in seconds, and then convert it to days. 

// Assuming $dbDate is the date retrieved from the database
$dbDate = "2022-01-15";
$currentDate = date("Y-m-d");

$dbTimestamp = strtotime($dbDate);
$currentTimestamp = strtotime($currentDate);

$diffInSeconds = $currentTimestamp - $dbTimestamp;
$diffInDays = $diffInSeconds / (60 * 60 * 24);

echo "The difference in days is: " . $diffInDays;
