无关的复选框？不知道他们来自哪里

Question

这是代码。

<?php
$dirname = 'music';

$dir = new DirectoryIterator($dirname);

foreach ($dir as $path => $splFileInfo)
{
if ($splFileInfo->isDir())
    continue;


 $output = explode(' ', $splFileInfo, 5);
echo "<form>";
?><input type="checkbox" name="<?php echo $output[0] ?>" /><?php echo "$output[0]"; ?>
<input type="checkbox" name="<?php echo $output[1] ?>" /><?php echo "$output[1]"; ?>
<input type="checkbox" name="<?php echo $output[2] ?>" /><?php echo "$output[2]"; ?>
<?php echo "</form>";

}
?>

这导致在编码的复选框之后有两个额外的复选框。示例：image since it won't let me post images yet.

我认为你试图在循环中做一些应该在它之外完成的事情。我期望基于代码的确切输出，所以让我在这里尝试修复：

<form action="" method="post">
<?php
$dirname = 'music';
$dir     = new DirectoryIterator($dirname);
foreach ($dir as $path => $splFileInfo)
{
    if ($splFileInfo->isFile())
    {
        $filename = $splFileInfo->getFilename();
        ?>
        <input type="checkbox" name="<?= $filename; ?>" /><label><?= $filename; ?></label><br />
        <?php
    }
}
?>
</form>
