PHP question ----- Reading EXIF data from image file.

This PHP code reads the EXIF data from an image file

Code:

<?php
$exif = exif_read_data('7.jpg', 0, true);

foreach ($exif as $key => $section) {
    foreach ($section as $name => $val) {
        echo "$key.$name: $val<br />\n";
    }
}
?>

The results are below.

Code:

FILE.FileName: 7.jpg
FILE.FileDateTime: 1696015524
FILE.FileSize: 175898
FILE.FileType: 2
FILE.MimeType: image/jpeg
FILE.SectionsFound: ANY_TAG, IFD0, EXIF, WINXP
COMPUTED.html: width="750" height="250"
COMPUTED.Height: 250
COMPUTED.Width: 750
COMPUTED.IsColor: 1
COMPUTED.ByteOrderMotorola: 1

I don't need all rows and columns. For example lets say I want to output only the 250 and 750 in this row:

COMPUTED.Height: 250
COMPUTED.Width: 750

The rows of data are 3 columns, the data I want is in the 3rd column.
How do I code that?
