add hours:min:sec to date in PHP

Question

I am trying to add hh:mm:ss with the date. How can i do it?

I tried with the following but it works when the hour is string, but when adding time is similar to MySQL

Answer 1

 print date('Y-m-d H:i:s',strtotime($timeA." +03 hour +05 minutes +01 seconds"));  

Should work also.

So:

$timeA= '2015-10-09 13:40:14'; 

$timeB = vsprintf(" +%d hours +%d minutes +%d seconds", explode(':', '03:05:01')); 

print date('Y-m-d H:i:s',strtotime($timeA.$timeB));

Can be the solution.
