How can a PHP developer avoid confusion between file-related functions and directory-related functions?

To avoid confusion between file-related functions and directory-related functions in PHP, developers should carefully read the documentation for each function before use. Additionally, using clear and descriptive variable names can help differentiate between files and directories in the code. 

// Example of using clear variable names to differentiate between file and directory functions

// File-related functions
$fileContents = file_get_contents('example.txt');
file_put_contents('newfile.txt', 'Hello, World!');

// Directory-related functions
$directoryContents = scandir('/path/to/directory');
mkdir('/path/to/new/directory');
