Hola, que tal:
tambien se puede hacer con la conversion de tipos; llamado casting o cast en el manual te dice como hacerlo.
por ejemplo:
variant_cast
(PHP 5)
variant_cast -- Convert a variant into a new variant object of another type
Description
variant variant_cast ( variant variant, int type )
This function makes a copy of variant and then performs a variant cast operation to force the copy to have the type given by type. type should be one of the VT_XXX constants.
This function wraps VariantChangeType() in the COM library; consult MSDN for more information.
See also variant_set_type().
