IntlChar::isUAlphabetic

(PHP 7, PHP 8)

IntlChar::isUAlphabetic — Check if code point has the Alphabetic Unicode property

public static IntlChar::isUAlphabetic ( mixed $codepoint ) : bool

Check if a code point has the Alphabetic Unicode property.

This is the same as IntlChar::hasBinaryProperty($codepoint, IntlChar::PROPERTY_ALPHABETIC)

codepoint: The int codepoint value (e.g. 0x2603 for U+2603 SNOWMAN), or the character encoded as a UTF-8 string (e.g. "\u{2603}")

Returns true if codepoint has the Alphabetic Unicode property, false if not.

Example #1 Testing different code points


<?php
var_dump(IntlChar::isUAlphabetic("A"));
var_dump(IntlChar::isUAlphabetic("1"));
var_dump(IntlChar::isUAlphabetic("\u{2603}"));
?>

以上例程会输出：

bool(true)
bool(false)
bool(false)

IntlChar::isalpha() - Check if code point is a letter character
IntlChar::hasBinaryProperty() - Check a binary Unicode property for a code point
IntlChar::PROPERTY_ALPHABETIC
