2、exif_read_data — 从一个图片文件中读取 EXIF 头信息。是一个 Exif 函数，依赖于扩展：Exif。查看 phpinfo 。未安装扩展：Exif。如图2
图2
3、本地环境为 Windows 10，查看扩展目录：C:\php-7.4.6\ext，文件 php_exif.dll 存在。如图3
图3
4、编辑文件 php.ini。取消 ;extension=exif 中的 ;。
修改前：
1 | ;extension=exif ; Must be after mbstring as it depends on it |
修改后：
1 | extension=exif ; Must be after mbstring as it depends on it |
5、查看 phpinfo 。已安装扩展：Exif。如图4

6、再次上传图片，未再报错。如图5
