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!
There is no way to remove a chunk in the middle of a file. You will need to read everything following the chunk to move it down to backfill the hole. Copying the relevant data to another file is an easy way to do this.
