Returns whether the type match. They match if type1 is compatible to type2.

Parameters

$var_info: The name of the type to check for whether it is compatible to type2.

$param_info: The type expression to check for.

bool $ancestors: (optional) Whether sub-type relationships for checking type compatibility should be taken into account. Defaults to TRUE.

Return value

bool Whether the types match.
