Description:
------------
using fread() on a file opened with fopen(..., "rb") will mis-read the file when magic_quotes_runtime is ON. According to documentation:

If magic_quotes_runtime is enabled, most functions that return data from any sort of external source including databases and ->text files<- will have quotes escaped with a backslash.



Reproduce code:
---------------
// TEST 1
set_magic_quotes_runtime(1);

$fp = fopen("bahor.zip", "rb");
$contents = fread($fp, filesize("bahor.zip"));
echo strlen($contents) . "\n";
echo filesize("bahor.zip") . "\n";
fclose($fp);

// TEST 2
set_magic_quotes_runtime(0);

$fp = fopen("bahor.zip", "rb");
$contents = fread($fp, filesize("bahor.zip"));
echo strlen($contents) . "\n";
echo filesize("bahor.zip") . "\n";
fclose($fp);


Expected result:
----------------
When I say binary I do mean binary, regardless of what some option claims. In the code above, the two sections should produce the same results, the exact size of the zip file.

Actual result:
--------------
In test 1 the sizes reported by filesize("bahor.zip") and strlen($contents) are different, due to the escaping which occurs because of magic_quotes_runtime being On
