lnmp安装exif扩展

1.找到位置

cd /usr/local/lnmp1.4-full/src

2.解压php

sudo bzip2 -d php-5.6.31.tar.bz2
sudo tar -xvf php-5.6.31.tar

3.进入php

cd /usr/local/lnmp1.4-full/src/php-5.6.31/ext

4.进入exif

 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

extension = "exif.so"

8.重启php

service php-fpm restart

9.查看

php -m

$ php -m |grep exif
exif

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']);
