Comments
The set() method takes a $comments parameter. If omitted (or set to null), any existing comment from the source file with be kept intact. If a $comment is provided it will overwrite the existing comment. Providing a zero-length $comment will cause the comment to be deleted.
Examples: Set a comment
Delete a comment
Keep existing comment

takes an $export variable as its 4th argument.
Example:

Read the Value of a Variable
The get method allows you to find the value of an existing given environment
variable. It returns false if the variable doesn't exist, or an array containing
the details of the line from the source file.
Source:
export ENV="dev" # dev or live?
Get command:
$writer->get('ENV');
Result:
Writing Blank/Comment Lines
The line method appends a single unprocessed line of output to the file. It could be used
to insert blank lines or comments. If you wish to append a new variable, the
set method should be used instead to prevent duplicates.
