But when you print it, it only shows two. that seems to me like a floating point precision issue. after all, the integer part of the microtime result is a quite big number... I even tried a workaround like $a = explode(' ', microtime()); echo $a[0] + $a[1]; but it resulted in the exact same result like microtime(true) anyone knows something for sure? greets Zoltán Németh > > Why is this? > > > Tomi Kaistila > PHP Developer > -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
