Bug description: fgets() problem
Description:
------------
0 in a text file does not have a length- it returns as an empty string;
however,the echo line below does echo a 0 to the screen. There is no way
to differentiate between a blank string and a string containing "0". I
have not tried this on unix system yet, but definately does not work on
windows.
Reproduce code:
---------------
while(!feof($handle))
{
$buffer= fgets($handle);
echo "$buffer";
if(strlen($buffer!=0))
{
$x=(int)($buffer);
$n=(int)($buffer);
Expected result:
----------------
it is a simple program that returns the word "ZERO"
if a 0 is in the buffer and returns a blank line if the buffer is empty.
Actual result:
--------------
a blank line is returned regardless if it is a 0 or a blank line. example
