cd exif && /usr/local/php/bin/phpize

5.配置

./configure --with-php-config=/usr/local/php/bin/php-config

6.安装

sudo make && sudo make install

7.增加配置

cd /usr/local/php/conf.d

sudo vim 008-exif.ini

8.重启php

service php-fpm restart

9.查看

php -m

$ php -m |grep exifexif

以下几种方式都可以

$file_arr = read_exif_data('./photo.jpg');$file_arr = read_exif_data('https://cdn.caomall.net/15344950781428748118.jpg');$file_arr = read_exif_data($_FILES[$file_name]['tmp_name']);
