IntlChar::forDigit

(PHP 7)

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

Description

public static IntlChar::forDigit ( int $digit [, int $radix = 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.

Parameters

digit

The number to convert to a character.

radix

The radix (defaults to 10).

Return Values

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

var_dump(IntlChar::forDigit(10));
var_dump(IntlChar::forDigit(10, 16));
