read_exif_data

Description

The read_exif_data() function reads the EXIF headers from a JPEG image file. It returns an associative array where the indexes are the Exif header names and the values are the values associated with those Exif headers. Exif headers tend to be present in JPEG images generated by digital cameras, but unfortunately each digital camera maker has a different idea of how to actually tag their images, so you can't always rely on a specific Exif header being present.

Example 1. read_exif_data <?php $exif = read_exif_data ('p0001807.jpg'); while(list($k,$v)=each($exif)) { echo "$k: $v<br>\n"; } ?> Output: FileName: p0001807.jpg FileDateTime: 929353056 FileSize: 378599 CameraMake: Eastman Kodak Company CameraModel: KODAK DC265 ZOOM DIGITAL CAMERA (V01.00) DateTime: 1999:06:14 01:37:36 Height: 1024 Width: 1536 IsColor: 1 FlashUsed: 0 FocalLength: 8.0mm RawFocalLength: 8 ExposureTime: 0.004 s (1/250) RawExposureTime: 0.0040000001899898 ApertureFNumber: f/ 9.5 RawApertureFNumber: 9.5100002288818 FocusDistance: 16.66m RawFocusDistance: 16.659999847412 Orientation: 1 ExifVersion: 0200
