示例1: isNameKnown
/**
* Determines if a time zone name is a known one.
*
* The method also searches among the backward compatible names.
*
* @param string $name The time zone name to be looked for (case-sensitive).
*
* @return bool `true` if the name is known, `false` otherwise.
*/
public static function isNameKnown($name)
{
assert('is_cstring($name)', vs(isset($this), get_defined_vars()));
$knownNamesWithBc = DateTimeZone::listIdentifiers(DateTimeZone::ALL_WITH_BC);
return CMap::find($knownNamesWithBc, $name) && self::isNameIcuCompatible($name);
}
示例2: find
/**
* Determines if a map contains a specified value.
*
* 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 $whatValue 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.
* @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 CComparator.html CComparator
