$string = '1902-03-25 18:25:25';
$timestamp = strtotime($string);
$mt0 = microtime(true);
$result1 = strtotime("$string +1 year");
$mt1 = microtime(true);
$result2 = strtotime("+1 year", $timestamp);
$mt2 = microtime(true);
printf("%.6f\r\n%.6f\r\n", $mt1-$mt0, $mt2-$mt1);
// This will output
// 0.000171
