note 39181 added to ref.w32api

In response to post by Jan Kleinsorge. To get the proper windows system uptime, one should use the Performance Monitoring system... GetTickCount is limited to 49.7 days, as the result is a dword. <?php if (!dl("php_w32api.dll")) { echo "Unable to load php_w32api.dll"; exit; } $api = new win32; $api->registerfunction("bool QueryPerformanceCounter (float &lpPerformanceCount) From kernel32.dll"); $api->registerfunction("bool QueryPerformanceFrequency (float &lpPerformanceFrequency) From kernel32.dll"); $api->QueryPerformanceCounter($a); $api->QueryPerformanceFrequency($b); $c = $a/$b; $days = floor($c / 86400); echo gmstrftime("System uptime is $days Days, %H Hr, %M Min, %S Sec<br>", $c); ?> The above snippet will return the true uptime for an unlimited time for a windows OS. (Disregarding the fact that windows needs reboot every 10 days or so :)) A tiny dange though is the lack of 64bit variable types in php.. (the "float &lpPerformanceCount" should be "long long &lpPerformanceCount") .. Nevertheless.. It works :) Philip S. ---- Manual Page -- http://www.php.net/manual/en/ref.w32api.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+39181 Delete -- http://master.php.net/manage/user-notes.php?action=delete+39181&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+39181&report=yes Search -- http://master.php.net/manage/user-notes.php
