    Hi there,

    I’ve been tinkering with trying to extract GPS EXIF data for a few days and have hit a brick wall. I thought that maybe I might be able to borrow some of the brainpower expressed here 🙂

    I’m using a test image that I know has GPS EXIF data included in it. I can use my mac’s preview app to display it. I upload it to wordpress and try to extract it, but there is no GPS data in the results I get from the exif_read_data() function. I’m baffled.

    Here is the function call I’m using to extract the EXIF data:

    $exif = @exif_read_data( $_FILES[‘media’][‘tmp_name’], 0, true );

    Here are the contents of the $exif variable after this call:

    exif: Array
    (
    [FILE] => Array
    (
    [FileName] => php35zLOg
    [FileDateTime] => 1269514888
    [FileSize] => 129219
    [FileType] => 2
    [MimeType] => image/jpeg
    [SectionsFound] => ANY_TAG, IFD0, EXIF
    )

    [COMPUTED] => Array
    (
    [html] => width=”700″ height=”525″
    [Height] => 525
    [Width] => 700
    [IsColor] => 1
    [ByteOrderMotorola] => 1
    )

    [IFD0] => Array
    (
    [Orientation] => 1
    [Exif_IFD_Pointer] => 38
    )

    [EXIF] => Array
    (
    [ColorSpace] => 1
    [ExifImageWidth] => 700
    [ExifImageLength] => 525
    )

    )

    Any hints would be greatly appreciated.

    Thanks,
