First of all, enable all errors and display them (see your php.ini
file). You will see your error.
You need to have something in your file before you can read it. Just
initialize it to 0 (numeric zero) with your favorite editor and it
should be ok.
Also, ensure the webserver userid has read/write access to the file.
And you have another potential problem which will show up sooner or
later - two different people accessing the file at the same time. You
may just lose one update - or you could screw up the file altogether.
You really need to lock the file from before you open it for reading
until after you close it for writing.
As for where to put it? Something like this can go anywhere between the
<body> and </body> tags - depends on where you want to display it.
But also, just forget it. A counter on a page is a sure sign of a
newbie (or someone who needs their ego stroked :-) ). Rather. use the
logs to get the information.
