isEmpty

isEmpty

Checks whether a specified directory is empty. It automatically handles both absolute paths and relative paths (falling back to the configured base path), and normalizes cross-platform directory separators (/ vs \).

Usage

isEmpty(string $folder): bool

Parameters

folder (string) : The directory path to check. Can be an absolute path or a path relative to $this->path.

Return Value

(bool) : Returns true if the folder exists and contains no files or subdirectories. : Returns false if the folder contains files/subdirectories, does not exist, or is unreadable due to permission issues.

📌 Since a standard empty directory contains . and .., a count of 2 or less subdirectories confirms the directory is empty.

Examples

1. Checking a relative path

If your base path (this->path) is set to /var/www/project/, you can check a subfolder like this:

$file->isEmpty('src')
// Checks: /var/www/project/src/

2. Checking an absolute path

You can also pass a full system path directly, bypassing the base path check:

$file->isEmpty('/var/www/project/src/')
