有没有一种很好的方法来反序列化PHP中的单个数组元素？

Is there a way to use PHP to unserialize individual array members?

Example - array of serialized objects

//$array
Array
(
    [0] => O:21:"Calc\Calc":22:{s:3:"qok";...
    [1] => O:21:"Calc\Calc":22:{s:3:"qok";...
    [2] => O:21:"Calc\Calc":22:{s:3:"qok";...
)

What I want is to transform it into an array of objects. For example, say I want to

1. unserialize them like I want
2. convert result into JSON

Is there was perhaps a way to do it like so:

$resultingJSON = '[' . implode(',', MAGIC_UNSERIALIZE_EACH($selections)). ']';
