如何在 scandir() php 中添加分页 [关闭]

我想在我的 'scandir' php 代码中添加分页，请帮助我如何在我的 php 代码中添加分页

这是我的代码

    <?

// image extensions
$extensions = array('3gp', 'mp4', 'png', 'gif', 'bmp');

// init result
$result = array();

// directory to scan
$directory = new DirectoryIterator('files/'.$_GET['dir'].'');

// iterate
foreach ($directory as $fileinfo) {
    // must be a file
    if ($fileinfo->isFile()) {
        // file extension
        $extension = strtolower(pathinfo($fileinfo->getFilename(), PATHINFO_EXTENSION));
        // check if extension match
        if (in_array($extension, $extensions)) {
            // add to result
            $result[] = $fileinfo->getFilename();
        }
    }
}
// print result

foreach($result as $files)
{

    echo "<div class='fl odd".(++$j%2==0 ? "2" : "")."'>";
    echo '<a class="fileName" href="file.php?file=files/'.$_GET['dir'].'/'.$files.'"><div><div><img src="thumb.php?dir=files/'.$_GET['dir'].'/'.$files.'" width="80" height="80" alt="'.$files.'" /></div><div>'.$files.'<br/><span>[Size : 32.74Mb]</span><br/></div></div></a></div>';}

现在，请解释一下如何在此代码中添加分页（页面），我想每页显示 10 个结果。

试试这个例子：

假设我们有index.php 文件

$perpage = 10;
$page = (int)$_GET['page'];
if(!($page>0)) $page = 1;
$offset = ($page-1)*$perpage;

$extensions = array('3gp', 'mp4', 'png', 'gif', 'bmp');
$files = glob('files/'.$_GET['dir'].'/*.'.'{'.implode(',', $extensions).'}', GLOB_BRACE);
$total_files = sizeof($files);
$total_pages = ceil($total_files/$perpage);
$files = array_slice($files, $offset, $perpage);
?>

<div>
    SHOWING: <?=$offset?>-<?=($offset+$perpage)?>  of <?=$total_files?> files
</div>

<?php foreach($files AS $file) : ?>
    <a class="fileName" href="file.php?file=files/<?=$_GET['dir']?>/<?=basename($file)?>">
        <?=basename($file)?>
    </a>
<?php endforeach; ?>




<a class="page" href="index.php?dir=<?=$_GET['dir']?>&page=<?=(($page-1>1)?($page-1):1)?>">
   <<
</a>

<?php for($p=1; $p<=$total_pages; $p++) : ?>
    <a class="page" href="index.php?dir=<?=$_GET['dir']?>&page=<?=$p?>">
        <?=$p?>
    </a>
<?php endfor; ?>

<a class="page" href="index.php?dir=<?=$_GET['dir']?>&page=<?=(($page+1>$total_pages)?$total_pages:($page+1)?>">
   >>
</a>
