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: "文件名" => $exif[FILE][FileName], "文件类型" => $imgtype[$exif[FILE][FileType]], 文件格式" => $exif[FILE][MimeType], "文件大小" => $exif[FILE][FileSize], "时间戳" => date("Y-m-d H:i:s",$exif[FILE][FileDateTime]), "图片说明" => $exif[IFD0][ImageDescription], "制造商" => $exif[IFD0][Make], "型号" => $exif[IFD0][Model], "方向" => $Orientation[$exif[IFD0][Orientation]], "水平分辨率" => $exif[IFD0][XResolution].$ResolutionUnit[$exif[IFD0][ResolutionUnit]], "垂直分辨率" => $exif[IFD0][YResolution].$ResolutionUnit[$exif[IFD0][ResolutionUnit]], "创建软件" => $exif[IFD0][Software], "修改时间" => $exif[IFD0][DateTime], "作者" => $exif[IFD0][Artist], "YCbCr位置控制" => $YCbCrPositioning[$exif[IFD0][YCbCrPositioning]], "版权" => $exif[IFD0][Copyright], "摄影版权" => $exif[COMPUTED][Copyright.Photographer], "编辑版权" => $exif[COMPUTED][Copyright.Editor], "Exif版本" => $exif[EXIF][ExifVersion], "FlashPix版本" => "Ver.
