 New Comment:

It's because they're totally different functions.
fsscanf() reads file from descriptor. Your example only reads first
line from the file, that being the \n char..

Description:
------------
fscanf on multiline input works differently than sscanf on exactly the
same data presented as a string.

Reproduce code:
---------------
<pre>
<?php
$str = "\n bla \nblup"; $file = "test.txt";
$fd = fopen($file, 'w'); fputs($fd, $str);
fclose($fd);
list($a,$b) = sscanf($str, ' %[a-z] %[a-z] ');
echo "$a;$b;\n";
$fd = fopen($file, 'r');
list($a,$b) = fscanf($fd, ' %[a-z] %[a-z] ');
fclose($fd);
echo "$a;$b;\n";
?>
</pre>


Expected result:
----------------
bla;blup;
bla;blup;


Actual result:
--------------
bla;blup;
;;
