How to show directory listing in alphabets to show directory in its Letter

本文关键字：显示列表字母表 | 更新日期: 2023-09-27

我有一个数组，它已经包含了按字母顺序排列的所有值：

目录列表：

Ahha
ah?

我只想列出第一个字母，每个字母的开头都是这样的：

A
___________________
Ahahhaa
Ah?

像这个

这是代码。

$alphabets = array('0-9','A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z');
$letter = list of directory.
foreach ($alphabets as $alphabet) { 
if ($letter[$alphabet])
echo '<a href="#letter-'.$alphabet.'">'.$alphabet.'</a>  '; 
else 
echo $alphabet.'  ';  
}

我需要根据字母表打印目录列表。

<?php
foreach ($letter[$alphabet] as $name) {
   echo $name;  
}
?>
$letter[$alphabet] == return nothing.

php v.5.5

是否正在尝试获取此信息？

$alphabets = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z');
$letter = array("Ahahah", "Bwahahah", "Ahow", "Catcw"); // is this what letters value?
foreach ($alphabets as $alphabet) {
  echo $alphabet;
  $match = null;
  foreach($letter as $let){
    preg_match("/[$alphabet]?/is", $let, $match);
    if(isset($match[0]) && $match[0]){
       echo '<a href="#letter-'.$alphabet.'">'.$let.'</a>  '; 
    }
  }
}

结果：A Ahahaha Ahow B Bwahhah C Catcw
