Description:
------------
fgets() does not load the binary data for unpack to process. If the fgets() function is replaced with fread() then the example below works as expected. The current documentation claims that fgets() is binary safe, which appears to be incorrect.

Test script:
---------------
<?php

    print "Saving...\n";
    $F=fopen('1.evid','wb');
    fwrite($F,pack('C6',65,66,67,68,69,70));
    fclose($F);
     
    print "Loading...\n";
    $F=fopen('1.evid','rb');
    $d=unpack('C6',fgets($F,6));
    print "Result: ".print_r($d,1)."\n";
    print count($d)."\n";
    fclose($F);


Expected result:
----------------
It should display an array with 6 values, as written to the file.

Actual result:
--------------
No data is read, the array is empty.
