You need to use unserialize(), as you said, with a foreach() loop, like this:

$arr = unserialize($dbString);

echo "<ul>";

foreach($arr as $key => $val)
{
    echo "<li>$val</li>";
}

echo "</ul>";

This will echo a list containing value because foreach() iterates through the unserialize()d array, as you have specified in your question.

The $key => $part is the icing on the cake for foreach(); if you want the get the array key, simply reference $key. If you want the data for that key, use $val.

If you want to echo just one element (your example is Internet), just don’t use a loop and reference it by key (integer):

$arr = unserialize($dbString);

echo $arr[2];

This echos the third element in the array on it’s own.
