PHP gets a time period timestamp and mktime () function

The Mktime () function returns the Unix timestamp of the date. The UNIX timestamp contains the number of seconds between the Unix era (January 1, 1970 00:00:00 GMT) and the specified time.

Grammar:
Mktime (hour,minute,second,month,day,year);

Instance:

    
     $d  = mktime(9, 12, 31, 6, 10, 2015);    echo"创建日期是 " . date("Y-m-d H:i:s", $d);?>

Common time stamp functions

/** * Get start and end Unix time period */Public Function Get_start_and_end_time ($mark)    {if($mark==' Yesterday ')        {$start _time= Mktime (0,0,0,Date(' m '),Date(' d ') -1,Date(' Y '));$end _time= Mktime (0,0,0,Date(' m '),Date(' d '),Date(' Y ')) -1; }Elseif($mark==' Today ')        {$start _time= Mktime (0,0,0,Date(' m '),Date(' d '),Date(' Y '));$end _time= Mktime (0,0,0,Date(' m '),Date(' d ') +1,Date(' Y ')) -1; }Elseif($mark==' Toweek ')        {$start _time= Mktime (0,0,0,Date(' m '),Date(' d ') -Date(' W ') +1,Date(' Y '));$end _time= Mktime ( at, -, -,Date(' m '),Date(' d ') -Date(' W ') +7,Date(' Y ')); }Elseif($mark==' Tomonth ')        {$start _time= Mktime (0,0,0,Date(' m '),1,Date(' Y '));$end _time= Mktime ( at, -, -,Date(' m '),Date(' t '),Date(' Y ')); }$arr[' Start_time '] =$start _time;$arr[' End_time '] =$end _time;return$arr; }
