mb_ord — Get Unicode code point of character

Description

function mb_ord(string $string, ?string $encoding = null): int|false

Returns the Unicode code point value of the given character.

This function complements mb_chr().

Parameters

string

A string

encoding

The encoding parameter is the character encoding. If it is omitted or null, the internal character encoding value will be used.

Return Values

The Unicode code point for the first character of string or false on failure.

Errors/Exceptions

As of PHP 8.0.0, a ValueError is thrown if encoding is an invalid encoding. Prior to PHP 8.0.0, an E_WARNING was emitted instead.

Changelog

Version Description
8.0.0 encoding is nullable now.
8.0.0 Now throws a ValueError if encoding is an invalid encoding. Previously, an E_WARNING was emitted and false was returned.

Examples

Example #1 A basic mb_ord() example

<?php
var_dump(mb_ord("A", "UTF-8"));
var_dump(mb_ord("🐘", "UTF-8"));
var_dump(mb_ord("\x80", "ISO-8859-1"));
var_dump(mb_ord("\x80", "Windows-1252"));
?>

The above example will output:


int(65)
int(128024)
int(128)
int(8364)
