The php date capture I am using

I am using php date capture

echo j7_getdate('Y-m-d','2010-11-15','+10 day');

function j7_getdate($format,$time='now',$ opt){
 return date("$format",strtotime("$time $opt"));
}

//Output 2010-11-25
//Detailed strtotime usage
/*
echo strtotime(" now"), "n";
echo strtotime("10 September 2000"), "n";
echo strtotime("+1 day"), "n";
echo strtotime("+1 week"), " n";
echo strtotime("+1 week 2 days 4 hours 2 seconds"), "n";
echo strtotime("next Thursday"), "n";
echo strtotime("last Monday"), "n" ";
