Description:
------------
Where is mb_substr function in version php 7.4.11?????

I use CodeIgniter framework and here's in many places the function. Please recover the mb_substr.

Thank you

Test script:
---------------
$val = "dfasfa";
echo strtoupper(mb_substr(trim($val), 0, 4));
Shows
Fatal error: Uncaught Error: Call to undefined function mbsubstr() in C:\xampp\htdocs\myproj\index.php:4 Stack trace: #0 {main} thrown in C:\xampp\htdocs\myproj\index.php on line 4

what about read the error message?
Call to undefined function mbsubstr()

mbsubstr != mb_substr

so the output is *for sure* not from "echo strtoupper(mb_substr(trim($val), 0, 4));"
are you kidding or why do you report own typos to a bugtracker?

Interactive shell

php > echo mb_substr('ggg', 1, 2);

php > $val = "dfasfa";
php > echo strtoupper(mb_substr(trim($val), 0, 4));
