Description:
------------
Linux web25 4.4.10-20160518-1030-f317965 #1 SMP Wed May 18 10:33:23 UTC 2016 x86_64

phpinfo() output attached.

using "exif_read_data('file')" fails to read data from jpeg files.

Code has worked in previous versions.

Also checked image online at http://exifdata.com/exif.php, shows EXIF data without issues.


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

$exif = exif_read_data( './2014-09-23-5981.jpg' ) ;
 
foreach ($exif as $mykey => $mysection) {
 foreach ($mysection as $myname => $myval) {
   echo "$mykey.$myname: $myval<br />\n";
   }
 }
						
?>

archive of example file and .jpeg here: http://www.indx.co.uk/phpexif.zip

Expected result:
----------------
Expected entire EXIF data, just got "COMPUTED" outputs.

Could you please confirm if this happens with the release of PHP 7.0.10 where a regression was recently fixed? I don't think it was merged to 5.6, but it would great if you could confirm that it works there

Sorry, I can't test with 7.10 - I've tried building it on my own systems but without success. My hosting provider offers 7.0.9, and this shows the same issues as I've noted with the 5.6.24 bug I've reported.

An update to this is that if I open an image with Photoshop, take out the EXIF information that I don't need (I only need the GPS-related data) then save, the GPS data is read ok. So it appears that it's an EXIF format issue, or some field that exif_read_data cannot parse.

However, this isn't a solution for me, as I have over 12,000 images.

Now I can "open"?

I have now had the opportunity to test for this bug on 7.0.10 - it is no longer present in that build. Would be great if you could merge this fix into the 5.6 builds. Thanks.

Have now also had the opportunity to test with 5.6.25, Which also fixes the bug. Thank you.
