exifreader

This extension allows you to read an EXIF data (including thumbnails) from your JPEG and TIFF images.

Example

Yii::import('application.extensions.exifreader.CExifReader');
or add to your config: 
'components'=>array(
    'CExifReader' => array(
        'class'=>'ext.exifreader.CExifReader',
    ),
),
then: 
$exifReader = new CExifReader;
// or $exifReader = Yii::app()->CExifReader;
 
$exif->file = PATH_TO_YOUR_FILE;
$data = $exif->getExifData(array(
    array('FILE', array('SectionsFound')),
    'COMPUTED',
    'THUMBNAIL',
    array('IFD0', array('UndefinedTag:0xC4A5')),
    array('EXIF', array('MakerNote')),
));
$thumbnail = $exif->getExifThumbnail();
