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)
