Will it make any difference or impact on my result, if I use substr() instead of mb_substr() function?

As my server does not have support for mb_ functions, I have to replace it with substr()

If you have utf-8 encoding use mb_substr

Example :

echo substr("hi mémé", 0 , 5); // will print hi m�
echo mb_substr("hi mémé", 0 , 5); // will print hi mé
