Static Methods

of()

char::of(int $code): string

---

ord()

char::ord(string $char): int

---

count()

char::count(int $code): int

Determines the number of {@code char} values needed to represent the specified character (Unicode code point). If the specified character is equal to or greater than 0x10000, then the method returns 2. Otherwise, the method returns 1.

---

compare()

char::compare(string $char1, string $char2): int

---

lower()

char::lower(string $char): string

---

upper()

char::upper(string $char): string

---

title()

char::title(string $char): string

---

isSpace()

char::isSpace(string $char): bool

---

isDigit()

char::isDigit(string $char): bool

---

isLetter()

char::isLetter(string $char): bool

---

isLetterOrDigit()

char::isLetterOrDigit(string $char): bool

---

isLower()

char::isLower(string $char): bool

---

isUpper()

char::isUpper(string $char): bool

---

isTitle()

char::isTitle(string $char): bool

---

isWhitespace()

char::isWhitespace(string $char): bool

---

isISOControl()

char::isISOControl(string $char): bool

---

isDefined()

char::isDefined(string $char): bool

Determines if a character is defined in Unicode.

---

isMirrored()

char::isMirrored(string $char): bool

Determines whether the specified character (Unicode code point) is mirrored according to the Unicode specification. Mirrored characters should have their glyphs horizontally mirrored when displayed in text that is right-to-left.

---

isLowSurrogate()

char::isLowSurrogate(string $char): bool

Determines if the given $char value is a Unicode low-surrogate code unit (also known as trailing-surrogate code unit).

---

isHighSurrogate()

char::isHighSurrogate(string $char): bool

Determines if the given $char value is a Unicode high-surrogate code unit (also known as leading-surrogate code unit).

---

isPrintable()

char::isPrintable(string $char): bool

---

number()

char::number(string $char): int

Returns the {@code int} value that the specified Unicode character represents.
