I want to delete a range of data from a text file using PHP. Let's assume the file contains the following:

Hello, World!

I want to delete everything from character 2 to character 7. The actual file I need to do this with is very large, so I don't want to have to read the large file in order to delete just a small, given range of data. The data contained within the given range is not known, so str_replace or preg_replace solutions wouldn't work anyways.

Thanks!
