Question

这是我的代码。我不知道为什么它不起作用。我试图用php for循环播放我的表格，但网站上没有显示任何内容。Nothing

这是我试图打印的二维数组。

这是我尝试用来打印的代码。

Dim valCheck As Variant

For i = 0 To row1
    For j = 0 To col1
        MsgBox ("started" & i)
        valCheck = Range("A1").Offset(i, j).Value
        MsgBox (valCheck)
        If valCheck = "Details" Then
            MsgBox ("found")
            ActiveCell = Range("A1").Offset(i + 1, j)
            Exit For
            Exit For
        End If
    Next j
Next i

Answer 1

您必须使用foreach作为foreach (array_expression as $value)

foreach构造提供了一种迭代数组的简单方法。 foreach仅适用于数组和对象，并在发生时发出错误您尝试在具有不同数据类型或变量的变量上使用它未初始化的变量。

像：

<?php
$weapons = array(
 array("Type 1",1,78906,"Apple","R1"),
 array("Type 2",2,78915,"Javascript","R4"),
 array("Type 3",3,78933,"Red","R6"),
 array("Type 4",4,78934,"Circle","R1"),
 array("Type 5",1,1167552,"Fried rice","R4"),
);
?>

<table border ="1">
     <tr>
      <th>Type</th>
      <th>Buttstock #</th>
      <th>Serial #</th>
      <th>Name</th>
      <th>Rank</th>
     </tr>
     <!--Put two-dimentinal arrays in the table-->
     <?php foreach ($weapons as $weapon) {?>
      <tr>
          <?php foreach ( $weapon as $val ) {?>
           <td><?php echo $val;?></td>
          <?php }?>
      </tr>
      <?php }?>
</table>

这将导致：

Doc：foreach

使用foreach增强Eddie的答案，
请注意，您可以直观地简化代码：

<!--Arrays of weapons-->
<?php
$weapons = array(
  array("M4A1",1,78906,"TUCKER, LISBETH","SPC"),
  array("M4A1",2,78915,"HATHAWAY, HANNAH","1LT"),
  array("M4A1",3,78933,"HARRIS, LEE","SFC"),
  array("M4A1",4,78934,"WELCH, BRAD","SSG"),
  array("M9",1,1167552,"BLAND, MARGARET","CPT"),
  array("M249",1,101032,"TYSON, MICHELLE","1SG"),
  array("M249",2,101038,"MEDINA, TOBIAS","SPC"),
  array("M240B",1,104104,"COSTA, JOSHUA","SSG"),
  array("M2A1",1,1863848,"GARCIA, RIGOBERTO","SSG"),
  array("MK-19",1,19369,"NEUPANE, KISHOR","SPC")
);
?>
<table border ="1">
 <tr>
  <th>Type</th>
  <th>Buttstock #</th>
  <th>Serial #</th>
  <th>Name</th>
  <th>Rank</th>
 </tr>
 <!--Put two-dimentinal arrays in the table-->
 <?php
  foreach ($weapons as $weapon) {
    echo '<tr>';
    foreach ( $weapon as $val ) {
        echo "<td>$val</td>";
    }
    echo '</tr>';
  } ?>
</table>

为何使用此解决方案？
因为php标签的多次打开和关闭会使代码难以阅读。
