PHP7のexif_read_dataがなんか変

PC

　php7になって、exif_read_dataがなんか変。
　以下はexif_read_dataで読み込んだデータ配列をprint_rしたもの。

Array
(
    [FileName] => DSC03874.JPG

    [COMPUTED] => Array
        (

            [Height] => 1944

    [FocalLength] => 470/100
)

　GPS系のデータが格納されていない。同じファイルをjheadしてみると

File name    : /home/kazz/Photo/20161016郡山若松/DSC03874.JPG
File size    : 1964293 bytes

　となっているので、GPS系のデータが書き込まれていないわけではない。なんでや。

検索してこんなの発見。

Hello,

I had the same issue and debugged it to the same problem (makernotes in exif).
I found a bug in PHP bug tracker which seems to be the cause of the issue :
https://bugs.php.net/bug.php?id=72682

I was using php 7.0.8. An upgrade to php 7.0.10 fixed the problem for me.

For ubuntu 16.04 I used this PPA :
https://launchpad.net/~ondrej/+archive/ubuntu/php

I'll add the same comment in Github issue #520 as it seems to be the same issue :
[Github] Piwigo issue #520

ありがちなバグってやつですか。アップグレードしてみる。

　無事戻りました。めでたしめでたし。

　しかし16.04 LTSでこんなバグのあるバージョンを標準のままにしているってどやねん。
