[development] Is it possible to serialize the output of a custom block and unserialize the value in a page.tpl.php ?

[Juan Rodriguez]

Hello,

I am trying to serialize the output of a block, which is received in a
page.tpl with the $content variable.

It seems it does not work, but I don't know why, because I can output
the serialized string (using $content)  in a page.tpl.php file
but if I try to unserialize it and afterwards try to print_r the
result, it shows nothing.

Does anybody have any clue? It seems quite weird to me...
