PHP - Scan dir for folders and txt - php

Question

I am dynamically building an accordion menu. Accordion will get the header information from folder names and contents from .txt files associated to folder names. They are relatives in terms of directory.
<div class="accordion">
<?php if($_GET['cat']!='') {
$handleCat = 'tv/'.$_GET['cat'];
$category = scandir($handleCat);
$i = 1;
foreach ($category as &$value) {if ((!in_array($value,array(".","..","...")))){
echo '<div class="header">'.$value.'</div><div class="content" id="ac'.$i.'">'.file_get_contents($value.".txt", false).'</div>';
$i+=1;}}}
?>
</div>
In my code there are two problems. First one is logic problem. I couldn't made up scan foldernames and file names seperately. Forexample program1.txt also becomes a headername. Second problem is method problem. I found file_get_contents() method but this doesn't extracts .txt file contents.

Answer 1

You can distinguish files from folders using the function is_dir().
As of file_get_contents, it reads the file contents but does not echo it. Use :
echo '<div class="header">'.$value.'</div>'.$value.'<div class="content" id="ac'.$i.'">';
echo file_get_contents($value.".txt", false);
echo'</div>';

Answer 2

Use the following to list files in a directory. Where I commented code you can do whatever you want with that particular file. You can use is_dir() to distinguish from files and directories and then proceed accordingly.
<?php
if ($dir = opendir('.')) {
while (false !== ($file = readdir($dir))) {
if ($file != "." && $file != "..") {
echo "$file\n";
//code
}
}
closedir($handle);
}
?>
Read the contents of a file using the following code.
$contents = file_get_contents($file);
