Description:
------------
Hello,

According to the documentation, the exif_read_data() allows to speficy the section 
we want to return.
It seems the section argument "FILE" is not being considered and return the same 
result if 0 argument was given.

Extension informations:

EXIF Version: 1.4 $Id: exif.c 314376 2011-08-06 14:47:44Z felipe $
Supported EXIF: Version	0220
Supported filetypes: JPEG,TIFF

Test script:
---------------
<?php
var_dump(exif_read_data(__DIR__ . 'sample-1.jpg', 'FILE', true));
?>

Expected result:
----------------
array(1) {
  ["FILE"]=>
  array(6) {
    ["FileName"]=>
    string(12) "sample-1.jpg"
    ["FileDateTime"]=>
    int(1320829793)
    ["FileSize"]=>
    int(162)
    ["FileType"]=>
    int(2)
    ["MimeType"]=>
    string(10) "image/jpeg"
    ["SectionsFound"]=>
    string(0) "COMPUTED"
  }
}


Actual result:
--------------
array(2) {
  ["FILE"]=>
  array(6) {
    ["FileName"]=>
    string(12) "sample-1.jpg"
    ["FileDateTime"]=>
    int(1320829793)
    ["FileSize"]=>
    int(162)
    ["FileType"]=>
    int(2)
    ["MimeType"]=>
    string(10) "image/jpeg"
    ["SectionsFound"]=>
    string(0) ""
  }
  ["COMPUTED"]=>
  array(4) {
    ["html"]=>
    string(22) "width="10" height="10""
    ["Height"]=>
    int(10)
    ["Width"]=>
    int(10)
    ["IsColor"]=>
    int(0)
  }
}
