php中目录列表的分页

我正在尝试获取目录列表脚本的分页

这是函数的原始代码。 此功能列出目录中的所有mp3文件和一些文件信息

$songs

正在保存数组信息

foreach ($songs as $song => $opts)

编辑代码

 foreach ($pages[$pgkey] as $song => $opts) {

正常

我自己解决了这个问题

这是解决办法

我使用数组_切片

$i = $stat_prev = 0;
$p = 1;
$currents = htmlspecialchars($_GET['showpage']);
$pages = array_chunk($songs, 10);
$t_pageshtml .= '<center>Page '.($currents+1).' of '.count($pages).'&nbsp;&nbsp;<br>Pages: ';
for($i=1; $i< count($pages)+1; $i++){
$t_pageshtml .= '<a href="?p='.htmlspecialchars($_GET["p"]).'&showpage='.($i-1).'">'.$i.'</a> &nbsp;';
}
$t_pageshtml .= '</center>';
$pgkey = (int)htmlspecialchars($_GET['showpage']);

$songs = array_slice($songs, $pgkey."0",10);

    foreach ($songs as $song => $opts ) {

$i=$stat\u prev=0；
$p=1；
$currents=htmlspecialchars（$_GET['showpage']）；
$pages=array_chunk（$songs，10）；
$t_pageshtml.='Page'（$currents+1）。'of'。计数（$pages）。'；
对于（$i=1；$i$opts形式的歌曲）{

您可以使用以下函数“分页”任何一维数组：

$pages = array_chunk($songs, $perPage = 10);
$pageCount = count($pages);
$currentPageSongs = $pages[$page-1]; # pages are zero-based

---

哦，天哪！所有这些都是为了列出一堆文件？12个全局文件？您是否能够将受影响的区域修剪成更小的代码段？您的代码中有很多非常强烈的代码味道！1）如果您必须向一个函数传递7个以上的参数，则会出现问题，您需要进行重构，通常这意味着要编写一系列更小的子函数s、 经验法则是每个任务一个函数。2）使用globals通常也是一种味道。它只是缺乏架构，是一种使变量可用的黑客行为，但它打破了所有封装和分离关注点的最佳实践。3）变量名中的下划线和缩写……等等。这是facebook的源代码吗？；）我的眼睛受伤了。@markus—“变量名中的下划线和缩写”现在你只是在挑剔；-）

$i = $stat_prev = 0;
$p = 1;
$currents = htmlspecialchars($_GET['showpage']);
$pages = array_chunk($songs, 10);
$t_pageshtml .= '<center>Page '.($currents+1).' of '.count($pages).'&nbsp;&nbsp;<br>Pages: ';
for($i=1; $i< count($pages)+1; $i++){
$t_pageshtml .= '<a href="?p='.htmlspecialchars($_GET["p"]).'&showpage='.($i-1).'">'.$i.'</a> &nbsp;';
}
$t_pageshtml .= '</center>';
$pgkey = (int)htmlspecialchars($_GET['showpage']);

$songs = array_slice($songs, $pgkey."0",10);

    foreach ($songs as $song => $opts ) {

$pages = array_chunk($songs, $perPage = 10);
$pageCount = count($pages);
$currentPageSongs = $pages[$page-1]; # pages are zero-based
