IntlChar::forDigit

(PHP 7, PHP 8)

IntlChar::forDigit — Get character representation for a given digit and radix

说明

public static IntlChar::forDigit(int $digit, int $base = 10): int

Determines the character representation for a specific digit in the specified radix.

If the value of radix is not a valid radix, or the value of digit is not a valid digit in the specified radix, the null character (U+0000) is returned.

The radix argument is valid if it is greater than or equal to 2 and less than or equal to 36. The digit argument is valid if 0 <= digit < radix.

If the digit is less than 10, then '0' + digit is returned. Otherwise, the value 'a' + digit - 10 is returned.

参数

digit

The number to convert to a character.

base

The radix (defaults to 10).

返回值

The character representation (as a int) of the specified digit in the specified radix.

示例

示例 #1 Testing different code points

<?php
var_dump(IntlChar::forDigit(0));
var_dump(IntlChar::forDigit(3));
var_dump(IntlChar::forDigit(3, 10));
var_dump(IntlChar::forDigit(10));
var_dump(IntlChar::forDigit(10, 16));
?>

以上示例会输出：

int(48)
int(51)
int(51)
int(0)
int(97)
