Description:
------------
If im trying to use the function gzfile() to a compressed file, that includes just a picture, the function don't read the complete file. On this reproduce, the function stops after the End Transmission Block.

Reproduce code:
---------------
$file=fopen("smiley1.gif","r");
$picture=fread($file,filesize("smiley1.gif"));
fclose($file);
$file=gzopen("smiley1.gz","w");
gzwrite($file,$picture);
gzclose($file);
//readgzfile("smiley1.gz"); With readgzfile, i get the correct picture information (132 Byte).
$file=gzfile("smiley1.gz");
print_r($file);

Expected result:
----------------
I expect to see all arrays until the end of the file.

Actual result:
--------------
With gzfile, i got just the array [0] with the content GIF89a
