Well, first of all, if you're going to do any web work, you need a local
development system to test on. This means duplicating as close as you
can the same software you have on your production system (NEVER do
development on a production system!).
And right now you have a number of different programs involved, any of
which can be causing a problem, even how you're handling the cut/paste
in your code.
fwrite() doesn't have a problem with writing double quotes to a file;
such a problem would render it pretty useless.
Listing the file to the terminal means display its contents on the local
terminal. Windows users would use the 'type' command; in *nix systems
the command is 'cat'. But you need to be at a command prompt on the
system with the file to use it (something you also need to be able to do).
What is in $txt immediately after the fwrite()?
BTW - you should NEVER use die() in production code. It terminates
processing of EVERYTHING (including the HTML) immediately, resulting in
invalid HTML being sent to the browser. Rather, you should test for
failure, and if it fails, just not execute the code dependent on the
operation working (and put out a failure message instead, if you wish).
You also realize your code is not multiprocessing safe. What happens,
for instance, if two people try to write to the same file at the same
time? Or after one person writes, a second one overwrites the file with
different data? There is no guarantee a filename passed in a URL is unique.
