Problem reading Exif data

[foucquet]

OK, so I am trying to read exif data from images and have come up against a snag that I cannot see the answer to. I know that what I have at present is pretty basic, but I want to be sure that I know how to access the bits I want before tidying it up into something more sophisticated. The coide I have is this:-

 

$exif = exif_read_data('brass jaw.jpg', 'EXIF');

$name = $exif['FileName'];
$height = $exif['ExifImageWidth'];
$width = $exif['ExifImageLength'];
$model = $exif['Model'];
$exposuretime = $exif['ExposureTime'];
$fnumber = $exif['FNumber'];
$iso = $exif['ISOSpeedRatings'];
$date = $exif['DateTime'];

echo "File Name: $name<br />";
echo "Height: $height<br />";
echo "Width: $width<br />";
echo "Camera: $model<br />";
echo "Shutter Speed: $exposuretime<br />";
echo "F number: $fnumber<br />";
echo "ISO: $iso<br />";
echo "Date & Time: $date<br />";

var_dump($exif);

 

This code produces the following:-

 

File Name: brass jaw.jpg

Height: 640

Width: 360

Camera: Canon EOS 550D

Shutter Speed: 244/1000000

F number: 8000000/1000000

ISO: Array

Date & Time: 2011:09:17 13:52:30

 

Which serves quite well apart from the ISO, which comes back as "Array". Now when I do a var_dump I see that ISOSpeedRatings returns as this:-

 

'ISOSpeedRatings' =>

array

0 => int 800

1 => int 800

 

What I can't work out is how to access the information from this - I know that the solution will probably be very simple, and that I will end up kicking myself, but I could use a little help.

It's a simple multidimensional array.

 

echo $iso['ISOSpeedRatings'][0];
echo $iso['ISOSpeedRatings'][1];

It's a simple multidimensional array.

 

echo $iso['ISOSpeedRatings'][0];
echo $iso['ISOSpeedRatings'][1];

 

That produces "Notice: Undefined index: ISOSpeedRatings" - I had thought of this but got the same result and couldn't work out why, which is why I resorted to the forum...

OK, problem solved replacing $iso with $exif did the trick - logical really, I just knew the solution would be simple...
