How can you calculate the expiration time of an access token in PHP based on the information provided by the API?

To calculate the expiration time of an access token in PHP based on the information provided by the API, you need to consider the current timestamp and the token's expiration time in seconds. By adding the expiration time to the current timestamp, you can determine when the token will expire.

$currentTimestamp = time(); // Get the current timestamp
$expirationTimeInSeconds = 3600; // Example: Token expires in 1 hour (3600 seconds)
$expirationTimestamp = $currentTimestamp + $expirationTimeInSeconds; // Calculate the expiration timestamp

echo "Token will expire at: " . date('Y-m-d H:i:s', $expirationTimestamp); // Display the expiration time in a readable format
