Calculate the PHP script execution time

Preface annual leave is coming soon. I want to do more work recently and help my tutor's company to tide over the difficulties. AlgorithmOf ArticleIt will be much less and may record some work gains. When I queried the database today, I felt that the script was executed for a long time. I wrote a function to calculate the execution time of the PHP script. Record the execution time of the microtime computing script.

/*** Description: Calculate the current time ** @ return float */function getcurrenttime () {list ($ msec, $ Sec) = explode ("", microtime ()); return (float) $ msec + (float) $ sec ;}

Example

$ Begin = getcurrenttime (); sleep (10); $ end = getcurrenttime (); $ spend = $ end-$ begin; echo "script execution time :". $ spend. "\ n ";

Note: Haha. it's relatively simple. record it for easy retrieval.
