sacar - php semanas entre 2 fechas

sacar los dias entre 2 fechas php

Question

hola cómo encontrar no de semanas y cada lunes fecha entre 2 fechas. por ejemplo, 10-07-2009 hasta hoy.

Nota : considere el año bisiesto y otras restricciones relacionadas con la fecha también.

Answer 1

Número de PHP de la semana entre 2 fechas de emisión

A continuación se muestra la solución (solución corregida para una pregunta hecha en el post - https://stackoverflow.com/questions/27560850/php-number-of-week-between-2-dates-issue ) para averiguar el no de semanas entre el intervalo de fechas.

Como la solución siguiente usa la diferencia de fecha, para incluir la fecha de inicio de la semana uno tendrá que usar la función de piso y para la inclusión de la fecha de fin de semana debe usarse el límite máximo, entonces solo devuelve el número correcto de semanas

$strtDate = ''2014-01-01'';
$endDate = ''2015-03-17'';

$startDateWeekCnt = round(floor( date(''d'',strtotime($strtDate)) / 7)) ;
// echo $startDateWeekCnt ."/n";
$endDateWeekCnt = round(ceil( date(''d'',strtotime($endDate)) / 7)) ;
//echo $endDateWeekCnt. "/n";

$datediff = strtotime(date(''Y-m'',strtotime($endDate))."-01") - strtotime(date(''Y-m'',strtotime($strtDate))."-01");
$totalnoOfWeek = round(floor($datediff/(60*60*24)) / 7) + $endDateWeekCnt - $startDateWeekCnt ;
echo $totalnoOfWeek ."/n";

Answer 2

Aquí hay una solución alternativa usando DateTime: -

function datediffInWeeks($date1, $date2)
{
    if($date1 > $date2) return datediffInWeeks($date2, $date1);
    $first = DateTime::createFromFormat(''m/d/Y'', $date1);
    $second = DateTime::createFromFormat(''m/d/Y'', $date2);
    return floor($first->diff($second)->days/7);
}

var_dump(datediffInWeeks(''1/2/2013'', ''6/4/2013''));// 21

Verlo funcionando

Answer 3

Este trabajo genial

function weeks_between($datefrom, $dateto)
    {
        $datefrom = DateTime::createFromFormat(''d/m/Y H:i:s'',$datefrom);
        $dateto = DateTime::createFromFormat(''d/m/Y H:i:s'',$dateto);
        $interval = $datefrom->diff($dateto);
        $week_total = $interval->format(''%a'')/7;
        return floor($week_total);

    }

weeks_between("25/02/2000 11:30:00","05/06/2015 11:29:59")

Answer 4

La siguiente función calcula las "semanas habladas" entre dos marcas de tiempo (es decir, lunes es la próxima semana si está en sábado).

function days_between($datefrom,$dateto){
    $fromday_start = mktime(0,0,0,date("m",$datefrom),date("d",$datefrom),date("Y",$datefrom));
    $diff = $dateto - $datefrom;
    $days = intval( $diff / 86400 ); // 86400  / day

    if( ($datefrom - $fromday_start) + ($diff % 86400) > 86400 )
        $days++;

    return  $days;
}

function weeks_between($datefrom, $dateto)
{
    $day_of_week = date("w", $datefrom);
    $fromweek_start = $datefrom - ($day_of_week * 86400) - ($datefrom % 86400);
    $diff_days = days_between($datefrom, $dateto);
    $diff_weeks = intval($diff_days / 7);
    $seconds_left = ($diff_days % 7) * 86400;

    if( ($datefrom - $fromweek_start) + $seconds_left > 604800 )
        $diff_weeks ++;

    return $diff_weeks;
}

Todos los números de la semana entre dos fechas en PHP

getNoOfWeek () devolverá el conjunto de la semana no. con año. Puede cambiar el formato de esta matriz desde week_text_alter ().

function getNoOfWeek($startDate, $endDate){
  // convert date in valid format
  $startDate = date("Y-m-d", strtotime($startDate));
  $endDate = date("Y-m-d", strtotime($endDate));
  $yearEndDay = 31;
  $weekArr = array();
  $startYear = date("Y", strtotime($startDate));
  $endYear = date("Y", strtotime($endDate));

  if($startYear != $endYear) {
    $newStartDate = $startDate;

    for($i = $startYear; $i <= $endYear; $i++) {
      if($endYear == $i) {
        $newEndDate = $endDate;
      } else {
        $newEndDate = $i."-12-".$yearEndDay;
      }
      $startWeek = date("W", strtotime($newStartDate));
      $endWeek = date("W", strtotime($newEndDate));
      if($endWeek == 1){
        $endWeek = date("W", strtotime($i."-12-".($yearEndDay-7)));
      }
      $tempWeekArr = range($startWeek, $endWeek);
      array_walk($tempWeekArr, "week_text_alter", 
         array(''pre'' => ''Week '', ''post'' => " ''". substr($i, 2, 2) ));
      $weekArr = array_merge($weekArr, $tempWeekArr);

      $newStartDate = date("Y-m-d", strtotime($newEndDate . "+1 days"));
    }
  } else {
    $startWeek = date("W", strtotime($startDate));
    $endWeek = date("W", strtotime($endDate));
    $endWeekMonth = date("m", strtotime($endDate));
    if($endWeek == 1 && $endWeekMonth == 12){
      $endWeek = date("W", strtotime($endYear."-12-".($yearEndDay-7)));
    }
    $weekArr = range($startWeek, $endWeek);
    array_walk($weekArr, "week_text_alter", 
       array(''pre'' => ''Week '', ''post'' => " ''". substr($startYear, 2, 2)));
  }
  $weekArr = array_fill_keys($weekArr, 0);
  return $weekArr;
}

function week_text_alter(&$item1, $key, $prefix)
{
  $item1 = $prefix[''pre'']. $item1 . $prefix[''post''];
}


Output 1 -
$weekArr = getNoOfWeek(''2014-01-01'', ''2014-02-10'');

Array
(
    [Week 1 ''14] => 0
    [Week 2 ''14] => 0
    [Week 3 ''14] => 0
    [Week 4 ''14] => 0
    [Week 5 ''14] => 0
    [Week 6 ''14] => 0
    [Week 7 ''14] => 0
)

Output 2 -
$weekArr = getNoOfWeek(''2013-12-01'', ''2014-02-10'');

Array
(
    [Week 48 ''13] => 0
    [Week 49 ''13] => 0
    [Week 50 ''13] => 0
    [Week 51 ''13] => 0
    [Week 52 ''13] => 0
    [Week 1 ''14] => 0
    [Week 2 ''14] => 0
    [Week 3 ''14] => 0
    [Week 4 ''14] => 0
    [Week 5 ''14] => 0
    [Week 6 ''14] => 0
    [Week 7 ''14] => 0
)

Answer 6

$diff = strtotime($dateto, 0) - strtotime($datefrom, 0);
echo floor($diff / 604800);
