I believe this is a concurrency problem...
2 PHP scripts can run at the same time and the problem is that your first
script gets as far as the unlink thus deleting the file. Then the 2nd script
is ran (at the same time) and trys to open the file which doesn't exist,
therefore it reads a num of 0. T
You could be having problems with multiple users, if two visitors come
at the same time file locking problems come into play, one script could
unlink the file at the same time another script tries to open it
resulting in an empty file.
A database would be a better way to do this, but assuming you

In theory yes. But it depends on your webserver. Search the archives.

Hi Mike,
I tried the first script you posted on the NG.
This is what happens when I copy and paste your script:
The formbox appears.
I insert a number.
I click submit.
The number reverts back to 0.
The URL script that you sent me works fine.
I'm using MS Win 98/ Apache / PHP 4
Please advise if
I won't keep it up long... but go here... you will see it works...

No dice Michael.
I treid both your scripts.
The formbox comes up.
I enter a number.
I hit submit.
The box clears out the entered number without any mes
This also works with the ternary operator... I don't think it likes the ++ because it
doesn't know the type yet.

You definitely want to use MySQL for this. Ignore all those people who
recommended text file DBs. They are /SLOW/. MySQL is very very fast. To
show you a small sample of how fast, here's the debug data from one of
my scripts, showing how long the page took to generate, and how many
queries were ru
tiple clients loading
pages.

If it should be fast,
avoid using mysql, just write a file with your number,
if there´s a new request, get your number, add one and write it back.
So you avoid mysql-"SQL parsing", opening Database, searching data,
send to process, php putting in var...
just open, read, add, write, close

You might also want to setup the table your updating the hits in
as a HASH type table which runs completely in RAM, and as a result
is extremely fast. The only obvious downside, is the data (or hits in this case)
are lost on reboot.

as long as you are only inserting information into the mysql db on each page
load, then you shouldn't have a problem. make sure you keep you indecies
down to a minimum.

It's very simple - at the top of every page, have a routine that opens a
text file, reads the number inside it into a variable, adds one, and writes
it back out again. If the text file doesn't exist, create it.
Psuedocode:
if (file exists) {
open file for reading;
read contents into $counter

How are you saving the current counter amount?
For instance if it's in a database, add a date field.
Check to see if the date is more than 24 hours old before displaying the
current counter. If it is then update the database and make the counter
number 0. If it's not older than 24 hours, just do

Yup, you need to have your key strings in quotes '',
so it doesn't think it's a constant.
