我正在使用 gmstrftime 但它对于我的 php 版本来说已经过时了

Question

我有以下代码片段：

function generate_calendar($year, $month, $days = array(), $day_name_length = 3, $month_href = NULL, $first_day = 0, $pn = array()){
  $first_of_month = gmmktime(0,0,0,$month,1,$year);
  $day_names = array();
  for($n=0,$t=(3+$first_day)*86400; $n<7; $n++,$t+=86400)
    $day_names[$n] = ucfirst(gmstrftime('%A',$t));
    $mes_pt = array('', 'Janeiro', 'Fevereiro', 'Março', 'Abril', 'Maio', 'Junho', 'Julho', 'Agosto', 'Setembro', 'Outubro', 'Novembro', 'Dezembro');

    list($month, $year, $month_name, $weekday) = explode(',',gmstrftime('%m,%Y,%B,%w',$first_of_month));
    $weekday = ($weekday + 7 - $first_day) % 7;

    $title   = htmlentities(ucfirst($mes_pt[(int)$month])).'&nbsp;'.$year;

    @list($p, $pl) = each($pn); @list($n, $nl) = each($pn);
       if($p) $p = '<span class="calendar-prev">'.($pl ? '<a href="'.htmlspecialchars($pl).'">'.$p.'</a>' : $p).'</span>&nbsp;';
       if($n) $n = '&nbsp;<span class="calendar-next">'.($nl ? '<a href="'.htmlspecialchars($nl).'">'.$n.'</a>' : $n).'</span>';
       $calendar = '<table class="calendar">'."\n".
          '<caption class="calendar-month"><h1><center><strong>'.$p.($month_href ? '<a href="'.htmlspecialchars($month_href).'">'.$title.'</a>' : $title).$n."</strong></center></h1></caption>\n<tr>";

        if($day_name_length){ 

           $calendar .= "<th bgcolor='black'><center><strong style='color: #FFFFFF'>Domingo</strong></th>";
           $calendar .= "<th bgcolor='black'><center><strong style='color: #FFFFFF'>Segunda</strong></th>";
           $calendar .= "<th bgcolor='black'><center><strong style='color: #FFFFFF'>Terça</strong></th>";
           $calendar .=  "<th bgcolor='black'><center><strong style='color: #FFFFFF'>Quarta</strong></th>";
           $calendar .= "<th bgcolor='black'><center><strong style='color: #FFFFFF'>Quinta</strong></th>";
           $calendar .= "<th bgcolor='black'><center><strong style='color: #FFFFFF'>Sexta</strong></th>";
           $calendar .=  "<th bgcolor='black'><center><strong style='color: #FFFFFF'>Sábado</strong></th>";

           $calendar .= "</tr>\n<tr>";
         }
                                                        
         if($weekday > 0) $calendar .= '<td colspan="'.$weekday.'">&nbsp;</td>';
}

我尝试更改以下代码

$day_names[$n] = ucfirst(gmstrftime('%A',$t));

和

list($month, $year, $month_name, $weekday) = explode(',',gmstrftime('%m,%Y,%B,%w',$first_of_month));

通过以下代码：

$day_names[$n] = datefmt_format('%A', $t);
list($month, $year, $month_name, $weekday) = explode(',', datefmt_format('%m,%Y,%B,%w', $first_of_month));

但是运行代码时出现以下错误：

致命错误：未捕获类型错误：datefmt_format()：参数 #1 ($formatter) 必须是 IntlDateFormatter 类型，给出字符串

你能帮忙解决吗？

我是这样解决问题的：

$fmt = new IntlDateFormatter(
   'pt-PT',
   IntlDateFormatter::FULL,
   IntlDateFormatter::FULL,
   'Europe/Lisbon',
   IntlDateFormatter::GREGORIAN,
   'EEEE'
);
$day_names[$n] = $fmt->format($t);

$fmt1 = new IntlDateFormatter(
  'pt-PT',
  IntlDateFormatter::FULL,
  IntlDateFormatter::FULL,
  'Europe/Lisbon',
  IntlDateFormatter::GREGORIAN,
  'm,Y,B,w'
);
list($month, $year, $month_name, $weekday) = explode(',',$fmt1->format($first_of_month));

我更新了这行代码

@list($p, $pl) = each($pn); @list($n, $nl) = each($pn);

对于

$index = 0;
foreach ($pn as $key => $value) {
  if ($index == 0) {
     $p = $key;
     $pl = $value;

  }elseif ($index == 1) {
     $n = $key;
     $nl = $value;

  }
  $index++;
}
