Description
public static int IntlChar::forDigit
( int $digit
[, int $radix = 10
] )
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.

var_dump(IntlChar::forDigit(10));
var_dump(IntlChar::forDigit(10, 16));
?>
The above example will output:
int(48)
int(51)
