ID: 63957 Comment by: bugzilla77 at gmail dot com Reported by: bugzilla77 at gmail dot com Summary: REQUEST_TIME_FLOAT too high Status: Wont fix Type: Bug Package: *Web Server problem Operating System: win32, apache module PHP Version: 5.5.0alpha2 Block user comment: N Private report: N New Comment: Maybe PHP should set the $_SERVER['REQUEST_TIME_FLOAT'] value to MIN of apr_time_as_msec() , microtime(true) ??????? Previous Comments: ------------------------------------------------------------------------ [2013-01-14 01:40:33] ahar...@php.net I can't reproduce this very reliably on either branch, so I don't think it's version specific as such. Changing $_SERVER['REQUEST_TIME_FLOAT'] to be microtime(true) on startup misses the point of what the server variable represents: it's what the Web server believes the request time to be, not when the PHP interpreter was invoked. If you want microtime(true), then set a variable to that at the top of your script. ------------------------------------------------------------------------ [2013-01-11 09:23:27] bugzilla77 at gmail dot com Why this problem is not found in PHP 5.4? ------------------------------------------------------------------------ [2013-01-11 09:21:20] bugzilla77 at gmail dot com Currently $_SERVER['REQUEST_TIME_FLOAT'] is useless in determining the time of generating web pages. I think that PHP should setting $_SERVER['REQUEST_TIME_FLOAT'] = microtime(true) on PHP's request handling. ------------------------------------------------------------------------ [2013-01-11 00:36:15] ahar...@php.net microtime() and $_SERVER['REQUEST_TIME_FLOAT'] use different mechanisms to get the time: microtime() calls gettimeofday() internally, whereas $_SERVER['REQUEST_TIME_FLOAT'] uses whatever method the SAPI provides to get the request time (for instance, the apache2handler SAPI calls apr_time_as_msec()). In practice, there are likely to be slight variances between the two methods, since they do different things. I don't see a sensible way we could change this without removing the semantics of $_SERVER['REQUEST_TIME_FLOAT'] actually being the server's request time (as opposed to just the startup time of PHP's request handling). Marking won't fix. ------------------------------------------------------------------------ [2013-01-10 10:28:44] bugzilla77 at gmail dot com Description: ------------ $_SERVER['REQUEST_TIME_FLOAT'] is greater than microtime(true) introduced in PHP 5.5 alpha (1-3) Test script: --------------- <?=$_SERVER['REQUEST_TIME_FLOAT']-microtime(true)?> Expected result: ---------------- positive float (PHP 5.4 OK) Actual result: -------------- negative float ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=63957&edit=1
