计算两个数据字段的平均值php / mysql

Question

I wonder know how to deal data format. I have 2 columns date(starting date) * date2 (end date) *. I am not familiar with php/mysql.

one my biggest clue is the data/data2 fields appears on this format ie. "1394797440". I am trying to build a dashboard with DB graphics of a ticket support. Had some features done but the data format is stressing me up. let me know if I am right.

I need to do a foreach on both fields? sorry my noob question but I am totally lost :|

mostly I use this call-> $call_date = date("m/d/y",$site_calls->call_date);

I will really appreciate any help.

Answer 1

The data/data2 format is most likely Unix epoch time. It is the number of seconds since Jan 1, 1970 and can be converted to an actual date and time.

Answer 2

This is a UNIX epoch datetime format ie number of seconds elapsed since 1st Jan, 1970. To take average of the two dates, it is similar to any other numeric average.

$avg_date = $site_calls->call_date + (($site_calls->call_date2 - $site_calls->call_date)/2);
$call_date = date("m/d/y",$avg_date);
