Is using explode() to split a string based on slashes a reliable method for extracting subdirectories in PHP?

Using explode() to split a string based on slashes can be a reliable method for extracting subdirectories in PHP. However, it's important to consider that explode() may not handle all edge cases, such as multiple consecutive slashes or different types of slashes (e.g., backslashes on Windows). To ensure more robust handling, you can use the built-in function dirname() in combination with explode() to extract subdirectories from a file path.

$file_path = "/path/to/directory/subdirectory/file.txt";
$subdirectories = explode('/', dirname($file_path));

print_r($subdirectories);
