When you need data, it seems better to use file contents.

For example, PHP has two corresponding functions, named file_get_contentsand file_put_contents. They are logical logical functions, but you can call their functions any way you want, as well. For example, the file_put_contents function can be implemented as a method..

Additional, note that file_get_contents() accepts offset and maxlen parameters. This tends to treat the file contents as a “sequence of bytes”.

If a file has, file_get_contents()

will return that file which had the requested format, up to a value of maxlen bytes.

Taken from file_get_contents() documentation : file_get_contents() returns the file in a string, starting at the specified offset up to maxlen bytes.
