How can PHP beginners ensure they are using the correct functions for file size manipulation?

PHP beginners can ensure they are using the correct functions for file size manipulation by referring to the official PHP documentation for file handling functions. They should pay attention to functions like `filesize()` for getting the size of a file in bytes, `number_format()` for formatting the size in a human-readable format, and `file_put_contents()` or `fwrite()` for writing data to a file. 

$file = 'example.txt';

// Get the file size in bytes
$fileSize = filesize($file);

// Format the file size in a human-readable format
$formattedSize = number_format($fileSize / 1024, 2) . ' KB';

echo "File size: $formattedSize";
