When should one use the chdir function in PHP and what are the potential drawbacks of using it in certain scenarios?

When one needs to change the current working directory in PHP, they can use the `chdir` function. This can be useful when working with files in different directories or when organizing file operations. However, it's important to be cautious when using `chdir` as it can affect the entire script and potentially cause confusion or errors if not used carefully.

// Change the current working directory to a specific folder
chdir('/path/to/directory');
