Bug #2829: writing in a file with fwrite()

From: arthur.angelier@iq3.nl Operating system: Windows NT PHP version: 3.0.11 PHP Bug Type: Other Bug description: writing in a file with fwrite() First of all, i like PHP verry much. It's an easy to learn and very usefull language. Still i have a little problem. I open a file with fopen() and i read in it with fread(). Then i set the filepointer with fseek() and i verify that action with ftell(). So far all goes well. But when i write to the file with fwrite(), i find that the bytes i wrote are always appended to the file and not written somewhere in the middle, at the position that i placed the filepointer on. So if i have a file with, let's say, 20 bytes (0 - 19), and i position the filepointer at byte 10, then i should be able to write in the middle of the file, right? This doesn't happen. And how can i truncate an opened file to a specific length? I want to truncate this file with 20 bytes to a length of 14 bytes. How can i do this?
