示例1: findScalar
/**
* Determines if a map contains a specified scalar value.
*
* If a map only contains values of scalar types i.e. `int`, `float`, `bool`, `string` (ASCII only), or `null`,
* this method allows for faster searches compared to `find` method. In case of `string` type, the search is
* case-sensitive.
*
* The `find` method would be of better service in searching for Unicode strings (the default comparator used by
* `find` method is Unicode-aware) and it was made flexible for you to be able to set your own comparison rules,
* such as making the search case-insensitive for any kind of strings.
*
* @param mixed $whatValue The searched value.
* @param reference $foundUnderKey **OPTIONAL. OUTPUT.** If a value has been found after the method was called
* with this parameter provided, the parameter's value is being the first key under which the value was seen. If
* the key is a string, its output type is `CUStringObject`.
*
* @return bool `true` if such value was found in the map, `false` otherwise.
*
* @link #method_find find
