Question

我没有使用php的经验，但我遇到了php的问题。

我有一个像这样的PHP代码：

<div>   
    <ul>
        <li><input type="checkbox" name="checkAll" 
                id="selectAll" class="checkbox"> Select All </li>

        <?php
            $count = 0;
            foreach ($caseList as $testcase)
            {
        ?>
            <li><input type="checkbox" name="testcases" 
                       class="checkbox" 
                       value="<?php echo $testcase->id; ?>">
                <?php echo $testcase->name; ?>
                <?php $count++;?>
            </li>
        <?php
            }
        ?>

        <li> <?php echo "Total Test Case COunt: $count";?> </li>
    </ul>

但我想在开始列表中打印“Total Test Case count”。我怎么能这样做？

Answer 1

将count($caseList)放在顶部。

<div>   
    <ul>
        <li><input type="checkbox" name="checkAll" id="selectAll" class="checkbox"> Select All </li>

        <li> <?php echo "Total Test Case COunt: " . count($caseList);?> </li>

        <?php
            $count = 0;
            foreach ($caseList as $testcase)
            {
        ?>

            <li><input type="checkbox" name="testcases" class="checkbox" value="<?php echo $testcase->id; ?>"><?php echo $testcase->name; ?><?php $count++;?></li>
        <?php
            }
        ?>



    </ul>

Answer 2

您可以尝试使用count函数获取没有计数器的数组长度。

$count = count($caseList);

所以你的最终代码可能就像

div>   
<ul>
    <li><input type="checkbox" name="checkAll" id="selectAll" class="checkbox"> Select All </li>

    <?php
        $total = count($caseList);
        echo "Total Test Case Count: $total"
        $count = 0;
        foreach ($caseList as $testcase)
        {
    ?>

        <li><input type="checkbox" name="testcases" class="checkbox" value="<?php echo $testcase->id; ?>"><?php echo $testcase->name; ?><?php $count++;?></li>
    <?php
        }
    ?>
</ul>

Answer 3

你需要从“li”标签移动增量

<div>   
<ul>
    <li><input type="checkbox" name="checkAll" 
            id="selectAll" class="checkbox"> Select All </li>

    <?php
        $count = 0;
        foreach ($caseList as $testcase)
        {
    ?>
        <li><input type="checkbox" name="testcases" 
                   class="checkbox" 
                   value="<?php echo $testcase->id; ?>">
            <?php echo $testcase->name; ?>
        </li>
    <?php
          $count++;
        }
    ?>

    <li> <?php echo "Total Test Case COunt: $count";?> </li>
</ul>

显示开始时的总计数值
