How Can I Recursively List Files from All Subdirectories in PHP?

List Files Recursively from All Subdirectories in PHP

In PHP, the list all files in a directory functionality can be extended to retrieve files from subdirectories recursively. This can be valuable for organizing and accessing files within complex directory structures.

Solution:

To recursively list files from all subdirectories, you can use the following code:

<code class="php">foreach (new RecursiveIteratorIterator(new RecursiveDirectoryIterator('.')) as $filename) {
    if ($filename->isDir()) {
        continue;
    }

    echo "$filename\n";
}</code>

Explanation:

  • RecursiveDirectoryIterator: Creates a new recursive directory iterator that iterates over files and directories in a given directory.
  • RecursiveIteratorIterator: Wraps the above iterator and provides additional filtering and processing capabilities.

Result:

The code creates an array-like structure ($files) containing all files from the current and all subdirectories. The output will be a list of files and their paths:

file.jpg
blah.word
name.fileext
