Question

我试图在下拉框一侧显示商店的状态，显示商店是打开还是关闭。下拉框中的状态是正确的，但下拉列表旁边的状态不正确。正确的一个值来自循环，我希望该值显示在循环外部。我正在使用的循环是foreach。请参阅附图以获得更好的理解。我得到了值但存储的最后一个值，我想要该行的第一个值。

我试图通过多种方式来解决这个问题，但到目前为止还没有运气。

我的代码是： -

<?php   

                 date_default_timezone_set('Australia/Melbourne');
                 $datetime = new \DateTime();

                 $listItem = array('<li class="active">', '</li>');

                 $curDay = date('l');

                 $status = array( "Now Open" ,"Closed",  "Opening Soon",  "Closing Soon", "Open 24 hours", "  ");


                  $times =  array(
                    1 => array('day' => 'Monday', 'open' => $oMon, 'close' => $cMon),
                    2 => array('day' => 'Tuesday', 'open' => $oTue, 'close' => $cTue),
                    3 => array('day' => 'Wednesday', 'open' => $oWed, 'close' => $cWed),
                    4 => array('day' => 'Thursday', 'open' => $oThur, 'close' => $cThur),
                    5 => array('day' => 'Friday', 'open' => $oFri, 'close' => $cFri),
                    6 => array('day' => 'Saturday','open' => $oSat, 'close' => $cSat),
                    7 => array('day' => 'Sunday', 'open' => $oSun, 'close' => $cSun));

                    $html= "" ;
                    $html .=  "<table class='table table-striped'  border='0' align='center' cellpadding='5' cellspacing='15'>";

  $i = 1;



$cd = $datetime->format('N'); 

$timenow =     date("H:i:s", time());


// Create an array of day numbers that start with current day and loops around
//$day_order = array_merge(range($cd, 7), range(1, $cd-1));

$day_order = range($cd, 7);
if ($cd != 1) {
    $day_order = array_merge($day_order, range(1, $cd-1));
}



 foreach ($day_order as $daynum): {
    $oc = $times[$daynum];
    $openingTime = $oc['open'];
    $closingTime = $oc['close'];
    $openingSoon = date('H:i:sA', strtotime($openingTime)-3600);
    $closingSoon = date('H:i:sA', strtotime($closingTime)-3600);
    if ($cd == $daynum) {
        if ($openingTime === null && $closingTime === null) {
            $s = $status[4];
        }
        elseif ($timenow < $openingSoon || $timenow > $closingTime ) {
            $s = $status[1];
        }
        elseif  ($timenow > $openingSoon && $timenow < $openingTime ) {
            $s = $status[2];
        }
        elseif  ($timenow > $closingSoon && $timenow < $closingTime ) {
            $s = $status[3];
        } else {
            $s = $status[0];
        }
    } else {
        $s = " ";
    }





    $html .=  "<tr>";
    $html .=  "<td  class='span2'>". $oc['day']."</td>";
   // echo  "<td>  <span class='white-text' style='margin-right: 3em;'> </td>";
    $html .=  "<td>".$openingTime."     ".$closingTime."</td>";
   // echo  "<td>  <span class='white-text' style='margin-right: 3em;'> </td>";
    $html .=  "<td  class='span2'>".$s."</td>";
    $html .= "</tr>";



}
      $datetime->add(new \DateInterval('P1D'));





  endforeach;
  $html .=  "</table>";
  echo $html;






   ?>

Hey Theodore Messinezis，我已经解决了这个问题......它太简单了......

我只需添加此

 $st = ""; // <- I added the declaration here
foreach ($day_order as $daynum): {

...
...
.

}
$st .= $s;//  <- I add this line inside the loop to get value outside the array

 endforeach;

echo $.st;  <- Output

PHP-在循环外显示单个值（在Laravel F / W上）
