In PHP, we can use the mb_ord() function to get the Unicode code point value of a given character. This function is supported in PHP 7 or higher versions. The mb_ord() function complements the mc_chr() function.
Syntax
int mb_ord($str_string, $str_encoding)
Parameters
mb_ord() accepts the following two parameters −
$str_string − This parameter is used for the string.
$str_encoding − This is the character encoding parameter. If it is absent or NULL, then we can use the internal encoding value.
Return Values
mb_ord() returns the Unicode point value for the first character from the given string. It will return False on failure.
Example
<?php
echo "Get the numeric value of character \n";
var_dump(mb_ord("B", "UTF-8"));
var_dump(mb_ord("d", "UTF-8"));
var_dump(mb_ord("\x80", "ISO-8859-2"));
var_dump(mb_ord("\x80", "Windows-1251"));
?>Output
It will produce the following output −
Get the numeric value of characters int(66) int(100) int(128) int(1026)
