示例1: countValue
/**
* Tells how many occurrences of a specified value there are in a map.
*
* You can use your own comparator for the search, but the default comparator has got you covered when searching
* for scalar values, such as `string`, `int`, `float`, and `bool`. And the default comparator is smart enough to
* know how to compare objects of those classes that conform to the IEquality or IEqualityAndOrder interface
* (static or not), including CUStringObject, CArrayObject, CMapObject, CTime etc. See the
* [CComparator](CComparator.html) class for more on this.
*
* @param mixed $value The searched value.
* @param callable $comparator **OPTIONAL. Default is** `CComparator::EQUALITY`. The function or method to be
* used for the comparison of values while searching. If this parameter is provided, the comparator should take two
* parameters, with the first parameter being a value from the map and the second parameter being the searched
* value, and return `true` if the two values are equal and `false` otherwise.
*
* @return int The number of such values in the map.
*
* @link CComparator.html CComparator

}示例2: testCountValue

// Using the default comparator.
$this->assertTrue(CMap::countValue($map, "c") == 5);
// Using a custom comparator.
$comparator = function ($string0, $string1) {
return CString::toLowerCase($string0) === CString::toLowerCase($string1);
};
