    <p>I've recently come across the php function <code>exif_read_data</code> - which is pretty awesome. I'm using it on my photography site, and while it works pretty well, I'm struggling to work out why <code>ApertureFNumber</code> isn't working. The code I'm using is:</p> <pre><code>$exif_data = exif_read_data($image[0]); echo $exif_data['Model']; echo $exif_data['ExposureTime']; echo $exif_data['FNumber']; echo $exif_data['ApertureFNumber']; echo $exif_data['ISOSpeedRatings']; echo $exif_data['DateTime']; </code></pre> <p>(<em>styling removed)</em></p> <p>I used <code>FNumber</code> as well as <code>ApertureFNumber</code> for testing because <code>FNumber</code> works, while <code>ApertureFNumber</code>just returns blank. All the other fields work fine.</p> <p>I did a var_dump of $exif_data - and this is what I get (the abridged version):</p> <pre><code>["ApertureFNumber"]=&gt; string(5) "f/3.5" ["FNumber"]=&gt; string(5) "35/10" </code></pre> <p>What have I missed that <code>FNumber</code> works, but <code>ApertureFNumber</code> doesn't?</p> <p>--</p> <p>EDIT - Complete var_dump added as requested</p> <pre><code>array(52) { ["FileName"]=&gt; string(18) "MYD-67-900x602.jpg" ["FileDateTime"]=&gt; int(0) ["FileSize"]=&gt; int(123278) ["FileType"]=&gt; int(2) ["MimeType"]=&gt; string(10) "image/jpeg" ["SectionsFound"]=&gt; string(30) "ANY_TAG, IFD0, THUMBNAIL, EXIF" ["COMPUTED"]=&gt; array(9) { ["html"]=&gt; string(24) "width="900" height="602"" ["Height"]=&gt; int(602) ["Width"]=&gt; int(900) ["IsColor"]=&gt; int(1) ["ByteOrderMotorola"]=&gt; int(0) ["ApertureFNumber"]=&gt; string(5) "f/3.5" ["FocusDistance"]=&gt; string(14) "4294967296.00m" ["Thumbnail.FileType"]=&gt; int(2) ["Thumbnail.MimeType"]=&gt; string(10) "image/jpeg" } ["Make"]=&gt; string(17) "NIKON CORPORATION" ["Model"]=&gt; string(9) "NIKON D60" ["XResolution"]=&gt; string(5) "200/1" ["YResolution"]=&gt; string(5) "200/1" ["ResolutionUnit"]=&gt; int(2) ["Software"]=&gt; string(41) "Adobe Photoshop Lightroom 4.4 (Macintosh)" ["DateTime"]=&gt; string(19) "2013:07:06 10:07:40" ["Exif_IFD_Pointer"]=&gt; int(216) ["THUMBNAIL"]=&gt; array(6) { ["Compression"]=&gt; int(6) ["XResolution"]=&gt; string(5) "200/1" ["YResolution"]=&gt; string(5) "200/1" ["ResolutionUnit"]=&gt; int(2) ["JPEGInterchangeFormat"]=&gt; int(932) ["JPEGInterchangeFormatLength"]=&gt; int(8995) } ["ExposureTime"]=&gt; string(5) "1/800" ["FNumber"]=&gt; string(5) "35/10" ["ExposureProgram"]=&gt; int(1) ["ISOSpeedRatings"]=&gt; int(100) ["ExifVersion"]=&gt; string(4) "0230" ["DateTimeOriginal"]=&gt; string(19) "2008:10:30 16:04:34" ["DateTimeDigitized"]=&gt; string(19) "2008:10:30 16:04:34" ["ShutterSpeedValue"]=&gt; string(15) "9643856/1000000" ["ApertureValue"]=&gt; string(13) "361471/100000" ["ExposureBiasValue"]=&gt; string(3) "0/6" ["MaxApertureValue"]=&gt; string(5) "36/10" ["SubjectDistance"]=&gt; string(4) "-1/1" ["MeteringMode"]=&gt; int(5) ["LightSource"]=&gt; int(0) ["Flash"]=&gt; int(0) ["FocalLength"]=&gt; string(4) "18/1" ["SubSecTimeOriginal"]=&gt; string(2) "50" ["SubSecTimeDigitized"]=&gt; string(2) "50" ["SensingMethod"]=&gt; int(2) ["FileSource"]=&gt; string(1) "" ["SceneType"]=&gt; string(1) "" ["CFAPattern"]=&gt; string(8) "" ["CustomRendered"]=&gt; int(0) ["ExposureMode"]=&gt; int(1) ["WhiteBalance"]=&gt; int(0) ["DigitalZoomRatio"]=&gt; string(3) "1/1" ["FocalLengthIn35mmFilm"]=&gt; int(27) ["SceneCaptureType"]=&gt; int(0) ["GainControl"]=&gt; int(0) ["Contrast"]=&gt; int(0) ["Saturation"]=&gt; int(0) ["Sharpness"]=&gt; int(0) ["SubjectDistanceRange"]=&gt; int(0) ["UndefinedTag:0xA431"]=&gt; string(7) "6265825" ["UndefinedTag:0xA432"]=&gt; array(4) { [0]=&gt; string(4) "18/1" [1]=&gt; string(4) "55/1" [2]=&gt; string(5) "35/10" [3]=&gt; string(5) "56/10" } ["UndefinedTag:0xA434"]=&gt; string(22) "18.0-55.0 mm f/3.5-5.6" } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
