PHP gets the number of days of the month and the date array based on the month

This article mainly introduces the method by which PHP obtains the number of days of the month and the date array according to the date, related to the relevant judgment, conversion and the traversal operation of the character and array of PHP, and the need of friends can refer to the following

Specific 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:

/*** gets the number of days in the month * @param $date * @param $rtype 1 days 2 specific date array * @return */function get_day ($date, $rtype = ' 1 ')  {    $tem = E Xplode ('-', $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 ';      $text = ' + ';    }    ElseIf ($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 ';      $text = ' a ';    }    if ($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 results of the operation 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 "}
