PHP-Handbuch: Get character representation for a given digit and radix

Beschreibung

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

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.

Parameter-Liste

digit: The number to convert to a character.
radix: The radix (defaults to 10).

Rückgabewerte

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