Try this code instead:

$f = fopen("./foo","r");
while (false !== ($c = fgetc($f))) {
    ...
}

As this is really what you want to do ;) The documentation for fgetc()
really needs to mention this as most others that might encounter this
0==false do (such as readdir).

A documention problem is to do the following to the fgetc docs:

a) Add an example that keeps in mind false vs 0
b) Implement the &return.falseproblem; entity.

here was my code:

$f=fopen("./foo","r");
while($c=fgetc($f)){
 ...
  }

...and the 'while' loop was quit long before EOF was reached.
After examination, it was quit when a character 0 was read
(thus confusion between 0 and EOF.......)

ok, it only true for non-blocking php streams ...

but still this should be mentioned on the fread() page

i asume this not only true for C fread() but also for PHP ?

if so -> should be documented as such ...
