In what situations should chdir be used instead of mkdir in PHP?

chdir should be used when you want to change the current working directory in your PHP script, while mkdir should be used when you want to create a new directory. If you need to navigate to a specific directory before creating a new one, you should use chdir to change to the desired directory first. 

// Change to a specific directory before creating a new one
chdir('/path/to/desired/directory');

// Create a new directory
mkdir('new_directory');
