note 113078 added to function.microtime

But note that the default 'precision' setting of PHP* - which is used when a float is converted to a stringy format by echo()ing, casting or json_encode()ing etc - is not enough to hold the six digit accuracy of microtime(true). Out of the box, microtime(true) will echo something like: 1377611450.1234 Which is obviously less than microsecond accuracy. You'll probably want to bump the 'precision' setting up to 16 which will echo something like: 1377611450.123456 *Internally* it will be accurate to the six digits even with the default 'precision', but a lot of things (ie. NoSQL databases) are moving to all-text representations these days so it becomes a bit more important. * 14 at the time of writing ---- Server IP: 69.147.83.199 Probable Submitter: 141.0.48.3 ---- Manual Page -- http://php.net/manual/en/function.microtime.php Edit -- https://master.php.net/note/edit/113078 Del: integrated -- https://master.php.net/note/delete/113078/integrated Del: useless -- https://master.php.net/note/delete/113078/useless Del: bad code -- https://master.php.net/note/delete/113078/bad+code Del: spam -- https://master.php.net/note/delete/113078/spam Del: non-english -- https://master.php.net/note/delete/113078/non-english Del: in docs -- https://master.php.net/note/delete/113078/in+docs Del: other reasons-- https://master.php.net/note/delete/113078 Reject -- https://master.php.net/note/reject/113078 Search -- https://master.php.net/manage/user-notes.php
