Exif-read-data, looping thru arrays/section - getting result

I'm trying to extract the exif information from an image with this foreach-loop and printing out for example the camera maker:

function readoutexifinfo($cur_image){
    $exif = exif_read_data($cur_image, 0, true);
    foreach ($exif as $key => $section) {   // $key IFD0; COMPUTED, ANY TAG, EXIF etc.
        foreach ($section as $name => $val) {
            if($key == "ANY_TAG"){
                echo $key.':'.$name.': '.$val."<br/>";
            }
            if($key == "FILE"){
                echo $key.':'.$name.': '.$val."<br/>";
            }
            if($key == "COMPUTED"){
                echo $key.':'.$name.': '.$val."<br/>";
            }
            if($key == "IFD0"){
                echo $key.':'.$name.': '.$val."<br/>";
            }
            if($key == "EXIF"){
                echo $key.':'.$name.': '.$val."<br/>";
            }
            if($key == "INTEROP"){
                echo $key.':'.$name.': '.$val."<br/>";
            }
        }
    }
    echo "Camera maker: ".$exif['IFD0']['make'];
}

The variabel $cur_image is predefined with an .jpg image. When i run this:

readoutexifinfo($cur_image);

I get this error message:

Notice: Undefined index: make

So my question is how can I get elements from ex. IFDO ['camera']['make'] ?

If that line is giving you that error, then the element $exif['IFD0']['make'] simply does not exist. Did you mean $exif['IFD0']['camera']['make'] ?
