Answer 1

Thanks a lot for Craig quick answer.

Used the unserialize method and got everything from the string.

Array
(
    [width] => 523
    [height] => 523
    [hwstring_small] => height='96' width='96'
    [file] => 2010/11/tee1.jpg
    [sizes] => Array
        (
            [thumbnail] => Array
                (
                    [file] => tee1-150x150.jpg
                    [width] => 150
                    [height] => 150
                )

            [medium] => Array
                (
                    [file] => tee1-300x300.jpg
                    [width] => 300
                    [height] => 300
                )

            [post-thumbnail] => Array
                (
                    [file] => tee1-523x198.jpg
                    [width] => 523
                    [height] => 198
                )

        )

    [image_meta] => Array
        (
            [aperture] => 0
            [credit] => 
            [camera] => 
            [caption] => 
            [created_timestamp] => 0
            [copyright] => 
            [focal_length] => 0
            [iso] => 0
            [shutter_speed] => 0
            [title] => 
        )

)

Here is the output, now can take any image from the wordpress post meta_data

Answer 2

What I understand is:

There are two types of variables, for example:

1. a:6:
2. s:3:

a = array and 6 is the dimension of the array
s = string and 3 is the length of the string

Answer 3

Try:

$a = unserialize("");
print_r($a);
