配置php.ini支持图片exif信息

本插件需要服务器具备EXIF扩展和mbstring扩展,而且mbstring扩展必须在EXIF扩展之前加载。



服务器配置说明:

1.在php.ini文件中找到;extension=php_exif.dll,去掉前面的分号

2.在php.ini文件中找到;extension=php_mbstring.dll,去掉前面的分号,并将此行移动到extension=php_exif.dll之前

3.找到[exif]段,把下面语句的分号去掉。

;exif.encode_unicode = ISO-8859-15

;exif.decode_unicode_motorola = UCS-2BE

;exif.decode_unicode_intel    = UCS-2LE

;exif.encode_jis =

;exif.decode_jis_motorola = JIS

;exif.decode_jis_intel    = JIS



不同的人可能需要不同的EXIF信息,下面这一段大家可以根据需要选用:
