How does the current working directory impact the calculation of file sizes in PHP when using functions like filesize()?

When using functions like `filesize()` in PHP, the current working directory affects the calculation of file sizes. If the file path provided to `filesize()` is relative, it will be relative to the current working directory. To ensure accurate file size calculations, it's important to set the correct working directory using `chdir()` before calling `filesize()`. 

// Set the desired working directory
chdir('/path/to/desired/directory');

// Get the file size
$fileSize = filesize('file.txt');

// Use the file size as needed
echo 'File size: ' . $fileSize . ' bytes';
