Writing to a file. (PHP)

[Nasimov]

It's possible to ammend data within a file vs. just adding data to the beginning or the end of the file? Mean to change something in the "middle" of the file.
Thanks.

Look at the list of PHP filesystem (http://www.php.net/filesystem) functions.

You can move a file pointer around in a file and read and write.

I think it would be easier to read the file into a buffer or array, manipulate the buffer and then write the buffer back to the file. This would also give you an abort option up till the write command.
