Description:
------------
Hi,
I've encountered the bug when trying to unzip a file into a full disk.

ZipArchive::extractTo reported true, but the extracted file had a 0 size.
It would be nice if extractTo had reported false, so I could have known something was wrong.

I've experienced the bug with debian php 5.3.6-7 and with php build from php5.3-201104071030.tar.bz2 with ./configure --enable-zip && make

May be php_zip_extract_file could return 0 if php_stream_write returns 0 in the n=zip_fread loop

PS: this bug may be the same as #53893 but as I'm unsure, I prefer to open a new one.

Test script:
---------------
function unzip ($file) {
    $za = new \ZipArchive();
    if ($za->open($file) === FALSE) {
        throw new Exception ("invalid zip file " . $file);
    }
    if ($za->numFiles != 1) {
        throw new Exception ("invalid zip file " . $file);
    }
    if (($archive = $za->getNameIndex(0)) === FALSE) {
        throw new Exception ("invalid zip file " . $file);
    }
    if ($za->extractTo('target', $archive) === FALSE) {
        throw new Exception ("could not extract archive " . $archive);
    }
    if ($za->close() === FALSE) {
        throw new Exception ("could not extract archive " . $archive);
    }
}

unzip('somefile.zip');

Expected result:
----------------
the script should throw an exception.

Actual result:
--------------
no exception is thrown.
