(PHP 7) Make Unicode character uppercase public static mixed IntlChar::toupper ( mixed $codepoint ) The given character is mapped to its uppercase equivalent. If the character has no uppercase equivalent, the character itself is returned. Parameters: codepoint The integer codepoint value (e.g. 0x2603 for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. "\u

(PHP 7) Make Unicode character titlecase public static mixed IntlChar::totitle ( mixed $codepoint ) The given character is mapped to its titlecase equivalent. If the character has no titlecase equivalent, the original character itself is returned. Parameters: codepoint The integer codepoint value (e.g. 0x2603 for U+2603 SNOWMAN), or the character encoded as a UTF-8 string

(PHP 7) Make Unicode character lowercase public static mixed IntlChar::tolower ( mixed $codepoint ) The given character is mapped to its lowercase equivalent. If the character has no lowercase equivalent, the original character itself is returned. Parameters: codepoint The integer codepoint value (e.g. 0x2603 for U+2603 SNOWMAN), or the character encoded as a UTF-8 string

(PHP 7) Return Unicode code point value of character public static int IntlChar::ord ( mixed $character ) Returns the Unicode code point value of the given character. This function compliments IntlChar::chr(). Parameters: character A Unicode character. Returns: Returns the Unicode code point value as an integer.

(PHP 7) Check if code point is a hexadecimal digit public static bool IntlChar::isxdigit ( mixed $codepoint ) Determines whether the specified code point is a hexadecimal digit. TRUE for characters with general category "Nd" (decimal digit numbers) as well as Latin letters a-f and A-F in both ASCII and Fullwidth ASCII. (That is, for letters with code points 0041..0046, 0061..0066, FF21..FF26, FF41..FF46.) This is equival

(PHP 7) Check if code point is a whitespace character according to ICU public static bool IntlChar::isWhitespace ( mixed $codepoint ) Determines if the specified code point is a whitespace character according to ICU. A character is considered to be a Java whitespace character if and only if it satisfies one of the following criteria: It is a Unicode Separator character (categories "Z" = "Zs" or "Zl" or "Zp"), but is not a

(PHP 7) Check if code point has the White_Space Unicode property public static bool IntlChar::isUWhiteSpace ( mixed $codepoint ) Check if a code point has the White_Space Unicode property. This is the same as IntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_WHITE_SPACE) Note: This is different from both IntlChar::isspace() and IntlChar::isWhitespace(). Parameters: cod

(PHP 7) Check if code point has the Uppercase Unicode property public static bool IntlChar::isUUppercase ( mixed $codepoint ) Check if a code point has the Uppercase Unicode property. This is the same as IntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_UPPERCASE) Note: This is different than IntlChar::isupper() and will return TRUE for more characters. Parameters: cod

(PHP 7) Check if code point has the general category "Lu" (uppercase letter) public static bool IntlChar::isupper ( mixed $codepoint ) Determines whether the specified code point has the general category "Lu" (uppercase letter). Note: This misses some characters that are also uppercase but have a different general category value. In order to include those, use IntlChar::isUUppercase(). Parameters:

(PHP 7) Check if code point has the Lowercase Unicode property public static bool IntlChar::isULowercase ( mixed $codepoint ) Check if a code point has the Lowercase Unicode property. This is the same as IntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_LOWERCASE) Note: This is different than IntlChar::islower() and will return TRUE for more characters. Parameters: cod
