The m_ord() is an inbuilt function in PHP that returns the Unicode code point for the specific character.
Syntax:
mb_ord(string $string, ?string $encoding = null): int|false
Parameters: This function has two parameters:
- string: This is the string input. It must be a valid string.
- encoding: The encoding parameter specifies the character encoding. In case if omitted or null, then the internal character encoding value will be utilized.
Return value: This function returns the first character Unicode if the function is successfully executed otherwise it will return “false”.
Example 1: The following code demonstrates the mb_ord() function.
PHP
<?php $string = '©'; $code_point = mb_ord($string, 'ISO-8859-1'); echo $code_point; ?> |
