How to add Pagination in scandir() php

本文关键字：php 添加分页 scandir | 更新日期: 2023-09-26

我想为我的'scandir' php代码添加分页，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，请告诉我如何在此代码中添加分页(页面)，我想显示每个页面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>

它可能工作，但你需要做一些改变，因为你的代码

$page_number = 1;
$count = 10;
$start_from = ($page_number - 1) * 10;
$end = $start_from + $count;

任意循环显示从$result[$start_from]到$result[$end]的数组值。

设置并发送下一个$page_number从显示区域到您的功能....
