Question

I wanted to see your input on this concern I’m currently experiencing.
It turns out that:

 <?php
$disc_t=$name; 
  if(strlen($disc_t)<=15)
  {
   $name_now=mb_substr( strip_tags($disc_t), 0, 10 ).'';
  }
  else
  {
   $name_now=mb_substr( strip_tags($disc_t), 0, 10).'...';
  }
?>

is somehow giving me an error on the site, the error shows:

Fatal error: Call to undefined function mb_substr() in /home/(website)/public_html/index.php on line 308

I don’t quite understand what they mean by mb_substr, is this a PHP version error?
I am currently using PHP 5.3.19

Answer 1

Throw this into a terminal:

php -m | grep mb

If mbstring shows up then it should work.
