How PHP gets the number of days and date arrays by month

This example describes how PHP obtains the number of days and date arrays by month. Share to everyone for your reference, as follows:

function Get_day ($date)  {    $tem = explode ('-', $date);//Cut date get year and month    $year = $tem [' 0 '];    $month = $tem [' 1 '];    if (In_array ($month, Array (1, 3, 5, 7, 8, (,),, (), ())    {      //$text = $year. '. $mont H. ' Month has 31 days ';      $text = ' + ';    }    ElseIf ($month = = 2)    {      if ($year%400 = = 0 | | ($year%4 = = 0 && $year%100!== 0))    Determines whether a leap        year {//$text = $year. '. $month. ' The month has 29 days ';        $text = ' $ ';      }      else{        //$text = $year. ' $month. ' The month has 28 days ';        $text = ' + ';      }    }    else{      //$text = $year. ' $month. ' The month has 30 days ';      $text = ' a ';    }    return $text;} echo get_day (' 2016-8-1 ');

Operation Result: 31

Transform, return an array of dates:

/*** get the number of days in the month * @param $date * @param $rtype 1 days 2 specific date array * @return */function get_day ($d    ate, $rtype = ' 1 ') {$tem = explode ('-', $date);    The cut date gets the year and month $year = $tem [' 0 '];    $month = $tem [' 1 ']; if (In_array ($month, Array (1, 3, 5, 7, 8, (,),, (), ()) {//$text = $year. '. $mont      H. ' Month has 31 days ';    $text = ' 31 '; } elseif ($month = = 2) {if ($year%400 = = 0 | |    ($year%4 = = 0 && $year%100!== 0))        Determines whether a leap year {//$text = $year. '. $month. ' The month has 29 days ';      $text = ' 29 ';        } else{//$text = $year. ' $month. ' The month has 28 days ';      $text = ' 28 ';      }} else{//$text = $year. ' $month. ' The month has 30 days ';    $text = ' 30 '; if ($rtype = = ' 2 ') {for ($i = 1; $i <= $text; $i + +) {$r [] = $year. " -". $month."      -". $i;    }} else {$r = $text; } return $r;} Var_dump (Get_day (' 2016-8-1 ', ' 2 ')); 

The

operation results are as follows:

Array (+) {[0]=> string (8) "2016-8-1" [1]=> string (8) "2016-8-2" [2]=> string (8) "2016-8-3" [3]=> string (8) " 2016-8-4 "[4]=> string (8)" 2016-8-5 "[5]=> string (8)" 2016-8-6 "[6]=> string (8)" 2016-8-7 "[7]=> string (8)" 20 16-8-8 "[8]=> string (8)" 2016-8-9 "[9]=> string (9)" 2016-8-10 "[10]=> string (9)" 2016-8-11 "[11]=> string (9)" 2016-8-12 "[12]=> string (9)" 2016-8-13 "[13]=> string (9)" 2016-8-14 "[14]=> string (9)" 2016-8-15 "[15]=> stri Ng (9) "2016-8-16" [16]=> string (9) "2016-8-17" [17]=> string (9) "2016-8-18" [18]=> string (9) "2016-8-19" [19]=&G T String (9) "2016-8-20" [20]=> string (9) "2016-8-21" [21]=> string (9) "2016-8-22" [22]=> string (9) "2016-8-23" [23 ]=> string (9) "2016-8-24" [24]=> string (9) "2016-8-25" [25]=> string (9) "2016-8-26" [26]=> string (9) "2016-8- "[27]=> string (9)" 2016-8-28 "[28]=> string (9)" 2016-8-29 "[29]=> string (9)" 2016-8-30 "[30]=> string (9)" 2 016-8-31 "}

The above is PHP based on the date of the month to obtain the number of days and the method of the array of content, more relevant content please pay attention to topic.alibabacloud.com (www.php.cn)!
