我的问题是我想在循环之外回显$ problem。当我这样做时，它仅包含1个值。所以我在想是否有任何解决方案可以使$ problem不在括号内。在开始删除的模态中，我尝试回显$ problem，但是结果很喜欢我说只携带1个值，而不是数组... 所以我希望你们能成为我的向导，谢谢。...

Answer 1

然后您只需要使$ problem成为数组即可。将行更改为$problems[] = $row[1];

Answer 2

extension ViewController: CustomCellDelegate {
   func someFunctionToPassSomeValue(name: String) {
      print("Delegate is working. Value : \(name)")
   }
}

$(document).ready(function(){
    $("#myBtn").click(function(){
      var problem_statement = $(this).data('problem');
      $(".modal-body #problemText").val( problem_statement );
      $("#myModalDelete").modal('show');
    });
});

您可以使用一些JavaScript尝试一下吗？看来您的模态弹出窗口中需要这个$问题吗？ IMO将“ id”添加到您的按钮，在javascript中以及使用模式弹出窗口在回调集数据中附加click事件监听器。

Answer 3

就像这样：

$problem=array();
while (($row = oci_fetch_row($stid)) != false) {
  $problem[]=$row[1];
}

foreach($var in $problem){
  echo $var . "<br />"
}

Answer 4

当前，您正在覆盖先前的值，同时将数据添加到$ problem变量中。因此，您必须为此创建数组，并且需要将下一个值附加到现有数组中而不是覆盖。示例：

while (($row = oci_fetch_row($stid)) != false) {
      $def_usr[]     =$row[0];
      $problem[]     =$row[1];
      $solution[]    =$row[2];
      $def_date[]    =$row[3];
      $closed_date[] =$row[4];
      $count=$count+1;
}

在此while循环中，您将获得$problem的所有数组。如果您想在其他地方展示，请使用foreach loop。

示例：

if(!empty($problem)) {
    foreach($problem as $value ) {
       echo $value;
    }
}
