Question

我正在尝试创建一个具有特定<th>值的表格，我的数据如下：

Field Name, Field Value;Field Name, Field Value;Field Name, Field Value;

我在这样的foreach循环中使用了两个爆炸。

$custom_fields = $row{'custom_fields'};

$fields = explode(";", $custom_fields);

foreach ($fields as $field) {
    $cf = explode(',', $field);

    echo "<td>".$cf[1]."</td>";
}

这将根据需要输出数据，但数组中的值的数量会有所不同（总共有34个可能的值）。如何让空行显示没有值，或将它们留空？

我在寻找：

<table class="">
    <thead>
        <tr>
            <th nowrap>Choose your plan</th>
            <th nowrap>Month</th>
            <th nowrap>Day</th>
            <th nowrap>Year</th>
            <th nowrap>Street Address</th>
            <th nowrap>City</th>
            <th nowrap>State</th>
            <th nowrap>Zip</th>
            <th nowrap>Phone</th>
            <th nowrap>Alternate Phone</th>
            <th nowrap>Email Address</th>
            <th nowrap>Provider ID #</th>
            <th nowrap>I have read and understand the Terms and Conditions</th>
            <th nowrap>Total Plan Members</th>

            <th nowrap>Billing same as Shipping</th>
        </tr>
    </thead>
    <tbody>
    <tr>
    $custom_fields = $row{'custom_fields'};

    $fields = explode(";", $custom_fields);

    foreach ($fields as $field) {
        $cf = explode(',', $field);

        echo "<td>".$cf[1]."</td>";
    }
    </tr>

试试这个：

$custom_fields = $row{'custom_fields'};
$fields = explode(";", $custom_fields);
foreach ($fields as $field) {
  $cf = explode(',', $field);
  if(count($cf)== 2)
  {
     echo "<td>".$cf[1]."</td>";
  }
  else
  {
     echo "<td>No Value</td>";
  }
}

如何在php explode数组中处理空值？
