PHP Read Sub-Directories and Loop Through Files How To

PHP read sub-directories and loop through files how to?

Use RecursiveDirectoryIterator in conjunction with RecursiveIteratorIterator.

$di = new RecursiveDirectoryIterator('path/to/directory');
foreach (new RecursiveIteratorIterator($di) as $filename => $file) {
    echo $filename . ' - ' . $file->getSize() . ' bytes <br/>';
}

How to recursively iterate through files in PHP?

PHP has the perfect solution for you built in.

Example

// Construct the iterator
$it = new RecursiveDirectoryIterator("/components");

// Loop through files
foreach(new RecursiveIteratorIterator($it) as $file) {
    if ($file->getExtension() == 'html') {
        echo $file;
    }
}

• DirectoryIterator - Manual

PHP script to loop through all of the files in a directory?

You can use the DirectoryIterator. Example from php Manual:

<?php
$dir = new DirectoryIterator(dirname(__FILE__));
foreach ($dir as $fileinfo) {
    if (!$fileinfo->isDot()) {
        var_dump($fileinfo->getFilename());
    }
}
?>

How to list directories, sub-directories and all files in php

Use scandir to see all stuff in the directory and is_file to check if the item is file or next directory, if it is directory, repeat the same thing over and over.

So, this is completely new code.

function listIt($path) {
$items = scandir($path);

foreach($items as $item) {

    // Ignore the . and .. folders
    if($item != "." AND $item != "..") {
        if (is_file($path . $item)) {
            // this is the file
            echo "-> " . $item . "<br>";
        } else {
            // this is the directory

            // do the list it again!
            echo "---> " . $item;
            echo "<div style='padding-left: 10px'>";
            listIt($path . $item . "/");
            echo "</div>";
        }
    }
  }
}

echo "<div style='padding-left: 10px'>";
listIt("/");
echo "</div>";

You can see the live demo here in my webserver, btw, I will keep this link just for a second

When you see the "->" it's an file and "-->" is a directory

The pure code with no HTML:

function listIt($path) {
$items = scandir($path);

foreach($items as $item) {
    // Ignore the . and .. folders
    if($item != "." AND $item != "..") {
        if (is_file($path . $item)) {
            // this is the file
            // Code for file
        } else {
            // this is the directory
            // do the list it again!
            // Code for directory
            listIt($path . $item . "/");
        }
    }
  }
}

listIt("/");

the demo can take a while to load, it's a lot of items.

Loop through a directory and its sub-directories files in liquid

The short answer to your question is YES.

Solution

The Jekyll documentation guides you through displaying an index of all your _posts. Specifically, you will want something like the following:

<ul>
  {% for post in site.posts %}
    <li>
      <a href="{{ post.url }}">{{ post.title }}</a>
    </li>
  {% endfor %}
</ul>

I have tested this with subdirectories.

Explanation

Jekyll appears to ignore any folder structure inside of _posts while generating your _site. My _site has the following structure:

_posts/
    |
    post1.md
    subdirectory/
        |
        post2.md
_site/
    |
     2015/
        |
        08/
            |
            05/
                |
                post1.html
                post2.html

You can clearly see here that the subdirectory does not appear anywhere in your final site.

Extra credit

You can retrieve the original directory structure using {{ post.path }} and some careful string manipulation. However, at this point it's probably easier to just set the Category attribute in your YAML front matter. The category attribute can be retrieved with {{category}}.

Purely as an academic exercise, I went ahead and retrieved the directory.

  {% capture directory %}
      {% assign path = post.path | remove_first:'_posts/' | split:'/' %}
      {% for folder in path %}
          {% unless forloop.last %}
              {{ folder }}/
          {% endunless %}
      {% endfor %}
  {% endcapture %}
  Directory: {{directory}}

You can decide if this is useful.

Listing all the folders subfolders and files in a directory using php

function listFolderFiles($dir){
    $ffs = scandir($dir);

    unset($ffs[array_search('.', $ffs, true)]);
    unset($ffs[array_search('..', $ffs, true)]);

    // prevent empty ordered elements
    if (count($ffs) < 1)
        return;

    echo '<ol>';
    foreach($ffs as $ff){
        echo '<li>'.$ff;
        if(is_dir($dir.'/'.$ff)) listFolderFiles($dir.'/'.$ff);
        echo '</li>';
    }
    echo '</ol>';
}

listFolderFiles('Main Dir');

List all the files and folders in a Directory with PHP recursive function

Get all the files and folders in a directory, don't call function when you have . or ...

Your code :

<?php
function getDirContents($dir, &$results = array()) {
    $files = scandir($dir);

    foreach ($files as $key => $value) {
        $path = realpath($dir . DIRECTORY_SEPARATOR . $value);
        if (!is_dir($path)) {
            $results[] = $path;
        } else if ($value != "." && $value != "..") {
            getDirContents($path, $results);
            $results[] = $path;
        }
    }

    return $results;
}

var_dump(getDirContents('/xampp/htdocs/WORK'));

Output (example) :

array (size=12)
  0 => string '/xampp/htdocs/WORK/iframe.html' (length=30)
  1 => string '/xampp/htdocs/WORK/index.html' (length=29)
  2 => string '/xampp/htdocs/WORK/js' (length=21)
  3 => string '/xampp/htdocs/WORK/js/btwn.js' (length=29)
  4 => string '/xampp/htdocs/WORK/js/qunit' (length=27)
  5 => string '/xampp/htdocs/WORK/js/qunit/qunit.css' (length=37)
  6 => string '/xampp/htdocs/WORK/js/qunit/qunit.js' (length=36)
  7 => string '/xampp/htdocs/WORK/js/unit-test.js' (length=34)
  8 => string '/xampp/htdocs/WORK/xxxxx.js' (length=30)
  9 => string '/xampp/htdocs/WORK/plane.png' (length=28)
  10 => string '/xampp/htdocs/WORK/qunit.html' (length=29)
  11 => string '/xampp/htdocs/WORK/styles.less' (length=30)
