php的exif扩展

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，使之首先加载*。

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：
"文件名"                =>        $exif[FILE][FileName],
