PHP programming allows you to display the EXIF information of a photo and display the thumbnail effect in the image. The Code is as follows:

<? /*** Function for obtaining image information * a function for fully obtaining image information * @ access public * @ param string $ img image path * @ return array */function GetImageInfoVal ($ ImageInfo, $ val_arr) {$ InfoVal = "unknown"; foreach ($ val_arr as $ name => $ val) {if ($ name = $ ImageInfo) {$ InfoVal = & $ val; break ;}return $ InfoVal;} function GetImageInfo ($ img) {$ imgtype = array ("", "GIF", "JPG ", "PNG", "SWF", "PSD", "BMP", "TIFF (intel byte order)", "TIFF (motorola byte order )", "JPC", "JP2", "JPX", "JB2", "SWC", "IFF", "WBMP", "XBM "); $ Orientation = array ("", "top left side", "top right side", "bottom right side", "bottom left side", "left side top ", "right side top", "right side bottom", "left side bottom"); $ ResolutionUnit = array ("", "", "inches", "centimeters "); $ YCbCrPositioning = array ("", "the center of pixel array", "the datum point"); $ ExposureProgram = array ("undefined", "Manual", "label Quasi-program "," aperture prerequisite "," Shutter prerequisite "," depth of field prerequisite "," motion mode "," portrait mode "," Landscape mode "); $ MeteringMode_arr = array ("0" => "unknown", "1" => "average", "2" => "central key average light measurement ", "3" => "test", "4" => "partition", "5" => "evaluation", "6" => "local ", "255" => "other"); $ Lightsource_arr = array ("0" => "unknown", "1" => "daylight ", "2" => "Fluorescent Lamps", "3" => "tungsten lamps", "10" => "Flashlight", "17" => "standard lamps ", "18" => "standard light B", "19" => "standard light C", "20" => "D55", "21" => "D65 ", "22" => "D75", "255" => "Others"); $ Flash_arr = array ("0" => "flash did not fire", "1" => "flash fired", "5" => "flash fired but strobe return light not detected ", "7" => "flash fired and strobe return light detected",); $ exif = exif_read_data ($ img, "IFD0"); if ($ exif = false) {$ new_img_info = array ("File Information" => "no image EXIF information");} else {$ exif = exif_read_data ($ img, 0, true ); $ new_img_info = array ("FILE Information" => "-----------------------------", "FILE name" => $ exif [FILE] [FileName], "FILE type" => $ imgtype [$ exif [FILE] [FileType], "FILE Format" => $ exif [FILE] [MimeType], "FILE size" => $ exif [FILE] [FileSize], "timestamp" => date ("Y-m-d H: I: s ", $ exif [FILE] [FileDateTime]), "Image Information" => "-----------------------------", "Image Description" => $ exif [IFD0] [ImageDescription], "manufacturer" =>$ exif [IFD0] [Make], "Model" =>$ exif [IFD0] [Model], "direction" => $ Orientation [$ exif [IFD0] [Orientation], "horizontal resolution" => $ exif [IFD0] [XResolution]. $ ResolutionU Nit [$ exif [IFD0] [ResolutionUnit], "vertical resolution" => $ exif [IFD0] [YResolution]. $ ResolutionUnit [$ exif [IFD0] [ResolutionUnit], "Create Software" => $ exif [IFD0] [Software], "modification time" => $ exif [IFD0] [DateTime], "author" => $ exif [IFD0] [Artist], "YCbCr location control" => $ YCbCrPositioning [$ exif [IFD0] [YCbCrPositioning], "Copyright" => $ exif [IFD0] [Copyright], "photography Copyright" => $ exif [COMPUTED] [Copyright. photographer], "Edit Copyright" => $ exif [COMPUTED] [Copyright. editor], "Shooting information" => "---------------------------", "Exif version" => $ exif [EXIF] [ExifVersion], "FlashPix version" => "Ver.
