Can't get $cnt++ to work

[Wilfred Johnson]

I have a little simple hit counter. It works if I replace $cnt++;
with #cnt = $cnt + 1;
I can't see why this doesn't work. Any ideas?
if(file_exists("counter.dat")) {
$f = fopen("counter.dat", "r");
$cnt = fread($f, 10);
//echo "\n", "count 1 = ", $cnt, "\n";
fclose($f);
//$cnt++; DOESN'T WORK!!!
$cnt = $cnt + 1;
//echo "\n", "count 2 = ", $cnt, "\n";
$f = fopen("counter.dat", "w");
fwrite($f, $cnt);
fclose($f);
printf("\n%d people have visited this page\n", $cnt);
}

thanks,
Wilfred

What happens if you replace $cnt++ with ++$cnt?

This might not work, just an idea...

fclose($f);
//$cnt++; DOESN'T WORK!!!

Please use the following notation and your $cnt++ will work -
$cnt = (int) fread($f, 10);

Oh yeah, of course!
Disregard my answer earlier in this thread, it sucks!

So much for PHPs implicit types! :-p

I put it on my server, it works fine:

<?
if(file_exists("counter.dat")) {
$f = fopen("counter.dat", "r");
$cnt = fread($f, 10);
//echo "\n", "count 1 = ", $cnt, "\n";
fclose($f);
$cnt++;
//$cnt = $cnt + 1;
//echo "\n", "count 2 = ", $cnt, "\n";
$f = fopen("counter.dat", "w");
fwrite($f, $cnt);
fclose($f);
printf("\n%d people have visited this page\n", $cnt);
}
?>

If that doesn't work, then you need to break the code up into simpler
steps to find out why.

start with:
<?
$cnt=8;
$cnt++;
echo $cnt;

?>
If it says "9", which would be correct, then there's probably something
wrong with your original code. Just reconstruct the original code a
piece at a time until the error reappears.

I did cast the fread return to an int and it now works now. My php
is on linux and is version 4.3.7.

Of course... I've heard complaints about this before, but alas, I don't
know what causes it.
I'm trying a new setting now, so if it's alright, please tell me so.

I'm using Sylpheed-Claws (as you can see in my X-Mailer header), so if
anyone knows how to make it _not_ attach the messages I'd be very
delighted to hear it.

Yeah, the other people complaining about my posts being attachments also
use OE. But I guess I'll just use the inline PGP signature then. Unless
somebody tells me that it is highly non-standard.

Heh.. now wait for the other complaints Anders.. about your sig exceeding
4 lines ;)

FWIW.. I'm not complaining.. the inline version works fine reading it in
Pan (windoze and FreeBSD) and the signed single version also works.. but
from past experience, people dislike this [sigh]. I used to use PGP to
post to most groups too.. as I used to frequent alt.comp.virus regularly..
in some groups more than others, signing posts made sense.. and searching
google for my unmunged address in this post will reveal some idiotic posts
to spam, virus and some suicide groups courtesy of some kid who didn't
like a response I made (kids will be kids I guess) which outlines why I
personally think signing has some benefit.. but I ended up dropping the
lot to keep the peace.

Hopefully you wont get hassled too.. but keep your fireproof suit handy =)

Hmm, I'd be very sorry to drop my PGP signature. (Are there no space for
security on Usenet?)
I've only begun using it recently and so far, the only complaint I've
had not being about my messages being attached in OE rather than an
actual RFC-822 mail, is one guy who questioned the actual usefulness of
PGP signatures on Usenet.
Hopefully you wont get hassled too.. but keep your fireproof suit

It doesn't happen often, but when you do get some idiot posing as you, the
sigs are useful.. especially if you don't "know" the person too well that
you're reading a post from (new to a group for example.. over time, you
get to recognise "styles"). alt.hacker is notorious for this unfortunately
as the script kiddies misunderstand the word 'hacker' so when they get
told to go and beg for cracks or how to get their "friend's" hotmail
password etc in a more relative group.. well let's just say brains don't
appear to come out in force. The last time was quite ironic when the kid
posted to a.c.virus from my unmunged address with a simple message of
"send me all your viruses" or something to the effect. The group's _anti_
virus for 99.9% of the time and seeing as I had been reading and posting
there for about 3 years, of all the groups he could have picked, that
wasn't the right one and the posts went ignored for the most part (anyone
who "knew me" anyway).. but it is annoying and many ISPs don't care.

Not everyone had issues with me doing it.. but my internal ISP newsgroups
went "mad" about it (like it was some kind of terrorist act or something
lol). I think c.l.php tends to be pretty relaxed.. compared to say,
c.l.perl.misc where you'd have your head bitten off twice per session.

I didn't _have_ to drop mine.. but when I ended up reading maybe 2 or 3
replies a day bitching about my "excessive, pointless sig" I gave up
(life's too short) =)

Oh and of course, the other argument was I was trying to prove how "3l33t"
I was... hmmmmmmm.. the mind boggles =)

I still sign all my mail however.

Ian

Yeah. Well, if that happens, I guess I'll drop mine as well, but I hope
people will just accept the fact that my posts are 190 bytes bigger than
necesarry, because I like them to be able to trust I am me...
But I'll see what happens, I guess.
