[Recursive function and too many foreach loop tangled]

 

So, how does this not do what you want:

<?php

const PATH = 'X:/testfolder1/Monthly Files';
const EXTENSIONS = ['doc', 'zip', 'pdf'];

$dirIterator = new RecursiveDirectoryIterator(PATH, RecursiveDirectoryIterator::SKIP_DOTS);
$fileIterator = new RecursiveIteratorIterator($dirIterator, RecursiveIteratorIterator::SELF_FIRST);

foreach ($fileIterator as $file)
{
    if ($file->isDir() || ($file->isFile() && in_array(strtolower($file->getExtension()), EXTENSIONS)))
    {
        echo "$file<br>";
    }
}

 

 

This will work, with basename this will list the directories and files.

const PATH = 'X:/testfolder1/Monthly Files';
const EXTENSIONS = ['doc', 'zip', 'pdf'];

$dirIterator = new RecursiveDirectoryIterator(PATH, RecursiveDirectoryIterator::SKIP_DOTS);
$fileIterator = new RecursiveIteratorIterator($dirIterator, RecursiveIteratorIterator::SELF_FIRST);

    
    echo basename(PATH);
    echo "<br><br>";

foreach ($fileIterator as $file)
{
    if ($file->isDir() || ($file->isFile() && in_array(strtolower($file->getExtension()), EXTENSIONS)))
    {
        echo basename($file)."<br>";
    }
}

output:

 

Monthly Files <------------root folder

 

February Files <----------------sub folder

February File 1.pdf

February File 2.pdf

File List.pdf <--------------root files

January Files <------------- sib folder

January File 1.pdf

January File 2.pdf

Read First.pdf <----------- root file

Zip File.zip <--------------- root file

 

How can I achieve this: List any root files in the root folder listing first, Then any sub folder and its contents listing?

 

Monthly Files <------------root folder

Read First.pdf <----------- root file

Zip File.zip <--------------- root file

File List.pdf <--------------root file

 

February Files <----------------sub folder

February File 1.pdf

February File 2.pdf

 

January Files <---------sub folder

January File 1.pdf

January File 2.pdf

 

[Recursive function and too many foreach loop tangled]

Oh, right, that was it.

 

I hope I am not confusing you? I dont want the results to have all files in one list and all directories in separate list. I dont mind the way code is listing the files and directories, but it is duplicating the results, if you look at my previous post you can see the files and directories of same name listing several times. How to fix that?

[Recursive function and too many foreach loop tangled]

Someone (I think it was me) originally suggested the RecursiveDirectoryIterator in another thread, but the output requirements made it easier to use scandir/glob and do the recursion manually.

 

...at least that's what I remember. I thought it was supposed to show files before directories too, but the posted code won't do that.

Mr requinix, I've posted this on devshed, I've taken your suggestions and got the codes to work this far, now stuck to this point. I've never done nested foreach loop before, I cant get foreach loop to behave correctly, listing same file and directory more than once? Also the root directory name should show on top and files inside it should show just below it but instead just get listed anywhere in the list of files.

 

After correcting the file_match($full_path, $patterns)

 

Also I've renamed few files so that I can follow what directory they belong to.

 

 

The output result I got:

 

February Files

February File 1.pdf

February File 2.pdf

February Files

February File 1.pdf

February File 2.pdf

February Files

February File 1.pdf

February File 2.pdf

File List.pdf

January Files

January File 1.pdf

January File 2.pdf

January Files

January File 1.pdf

January File 2.pdf

January Files

January File 1.pdf

January File 2.pdf

Read First.pdf

Zip File.zip

word.docx

 

 

Output should be like this:

 

 

Monthly Files

Read First.pdf

Zip File.zip

word.docx

 

January Files

January File 1.pdf

January File 2.pdf

 

February Files

February File 1.pdf

February File 2.pdf

[Recursive function and too many foreach loop tangled]

Note that PHP has several iterators and functions which can traverse directories just fine (and even filter the filenames). There's really no reason to implement that yourself.

I've tried with DirectoryIterator but I couldnt get it to work and the output result was not as expected. Would you be able to give examples of codes?

[Recursive function and too many foreach loop tangled]

I been banging my head over this for sometimes now, But I cant get the result I am after, I was hoping someone can liberate me from the forever circle of mistakes..

function file_match($file_path, array $patterns) {
    
    $files = array_diff(scandir($file_path), array('.', '..'));   
    
    foreach($files as $file) {
        
         $full_path = $file_path . DIRECTORY_SEPARATOR . $file; 
        
        foreach($patterns as $pattern) {
            
            if (is_file($full_path)) {
                
               if (fnmatch(strtolower($pattern), $file)) {
                
                echo $file;
                echo "<br>";
                }
            
            } elseif (is_dir($full_path)) {
                
                echo $file;
                echo "<br>";
                
                file_match($full_path, $pattern);
            }
            
        }

    }
          
}

$file_path = 'X:/testfolder1/Monthly Files';

echo file_match($file_path, ['*.doc', '*.zip', '*.pdf]);

Expecting result:

 

Directory1

List of files resides inside this directory

 

Directory 2

List of files Resides inside this directory

 

etc

 

like:

 

This is what it should be:

Monthly Files
Test File Main 2.PDF
Test File Main 1.doc

January Files
File January 1.PDF
File January 2.zip

February Files
Files February 1.PDF
Files February 2.PDF

 

etc
