normalizer_get_raw_decomposition
( string $input
) : string
Gets the Decomposition_Mapping property, as specified in the Unicode Character Database (UCD), for the given UTF-8 encoded code point.
参数
input- The input string, which should be a single, UTF-8 encoded, code point.
返回值
Returns a string containing the Decomposition_Mapping property, if present in the UCD.
Returns null if there is no Decomposition_Mapping property for the character.
范例
Example #1 Normalizer::getRawDecomposition() example
<?php$result = "";$strings = [ "a", "\u{FFDA}", "\u{FDFA}", "", "aa", "\xF5",];foreach ($strings as $string) { $decomposition = Normalizer::getRawDecomposition($string); // $decomposition = normalizer_get_raw_decomposition($string); Procedural way $error_code = intl_get_error_code(); $error_message = intl_get_error_message(); $string_hex = bin2hex($string); $result .= "---------------------\n"; if ($decomposition === null) { $result .= "'$string_hex' has no decomposition mapping\n" ; } else { $result .= "'$string_hex' has the decomposition mapping '" . bin2hex($decomposition) . "'\n" ; } $result .= "error info: '$error_message' ($error_code)\n";}echo $result;?>
以上例程会输出：
--------------------- '61' has no decomposition mapping error info: 'U_ZERO_ERROR' (0) --------------------- 'efbf9a' has the decomposition mapping 'e385a1' error info: 'U_ZERO_ERROR' (0) --------------------- 'efb7ba' has the decomposition mapping 'd8b5d984d98920d8a7d984d984d98720d8b9d984d98ad98720d988d8b3d984d985' error info: 'U_ZERO_ERROR' (0) --------------------- '' has no decomposition mapping error info: 'Input string must be exactly one UTF-8 encoded code point long.: U_ILLEGAL_ARGUMENT_ERROR' (1) --------------------- '6161' has no decomposition mapping error info: 'Input string must be exactly one UTF-8 encoded code point long.: U_ILLEGAL_ARGUMENT_ERROR' (1) --------------------- 'f5' has no decomposition mapping error info: 'Code point out of range: U_ILLEGAL_ARGUMENT_ERROR' (1)
