IntlChar::forDigit
(PHP 7, PHP 8)
IntlChar::forDigit — Get character representation for a given digit and radix
Description
$digit, int $base = 10): intDetermines 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.
-
base -
The radix (defaults to
10).
Return Values
The character representation (as a string) of the specified digit in the specified radix.
Examples
Example #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));
?>
The above example will output:
int(48) int(51) int(51) int(0) int(97)
