Question

这可能是我忽略的一个简单原因，但我的第二个if语句，一个条件为sizeof（$ duplicate）＆gt; 0，运行不正常。尽管我已经验证$ duplicate的大小实际上是0，并且段落标签下没有显示列表，但仍然显示html块。我错过了什么吗？

<html>
<head>
</head>
<body>
    <?php echo (sizeof($duplicate)); ?>
    <?php if(sizeof($not_exist > 0)) : ?>
        <p>The following companies were not updated because their Company Name did not exist in database: </p>
        <ul>
            <?php foreach($not_exist as $entry) {
                echo "<li>Company Name: " . $entry . "</li>";
            }
            ?>
        </ul>
    <?php endif; ?>
    <?php if(sizeof($duplicate > 0)) : ?>
        <p>The following companies had more than 1 entry under the same Company Name in database:</p>
        <ul>
            <?php foreach($duplicate as $entry) {
                echo "<li>Company Name: " . $entry . "</li>";
            }
            ?>
        </ul>
    <?php endif; ?>
    <?php if(sizeof($failed > 0)) : ?>
        <p>The following companies were not updated because the new Display Name already exists in QuickBooks:</p>
        <ul>
            <?php foreach($failed as $entry) {
                echo "<li>Company Name: " . $entry . "</li>";
            }
            ?>
        </ul>
    <?php endif; ?>
</body>

谢谢！
