call to undefined function mb_strimwidth
Solution 1
All mb_*
functions are provided by a PHP extension called Multibyte String, internal name mbstring
You probably don't have the extension active or installed. On most Linux distros you can install the package php-mbstring
to install and activate this extension.
Apache needs to be restarted afterwards if you are using mod_php
Solution 2
Just got this issue, if you are using linux just install the package php-mbstring
and restart Apache.
sudo apt-get install php-mbstring
sudo service apache2 restart
If you are using specific PHP version, you may need to run the following:
sudo apt-get install php7.x-mbstring
sudo service apache2 restart
Replace 7.x
by the exact PHP version.
Solution 3
u need to install php-mbstring
package try.
check php version
php -v
then check mbstring already install and enable
php -i | grep mbstring
if not installed run this command
sudo apt-get install php-mbstring
if you are php other version example : 7.1, 7.2, 7.0 based on run command like this :
sudo apt-get install php7.1-mbstring
if you are using nginx server for run laravel .. then check nginx configration file which version u have loaded in conf file..
go to cd /etc/nginx/sites-available
and open your configuration file..
if you are loading php7.2 version in nginx conf file..
fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
then u need to install 7.2 mbstring package..
sudo apt-get install php7.2-mbstring
and restart apache2 server
sudo service apache2 restart

Months ago I made a short code that uses
mb_strimwidth()
to exactly fit some text into a table cell, putting dots at the end of a truncated string. Now, after some times, I tried to execute that same code and it went out with this error:Fatal error: Call to undefined function mb_strimwidth() in ...
I tried to find the mbstring.php file, and when I found the
mb_strimwidth()
function, I discovered that it is not implemented anymore. How is that possible? But my main question is: how can I get the same result asmb_strimwidth()
? I thought to rewrite the function using a loop andmb_strwidth()
, but ALL the functions in that mbstring.php file are empty. -
Yuri over 11 yearsok, this solved my problem. But I don't understand what happened since last time, when it worked correctly...

Michel Feldheim over 11 yearsYou probably updated php, that's distro specific. e.g. installed php-54 packages and removed php packages.

Sijan Bhattarai almost 6 yearsI installed the php-mbstring in my machine and restarted the apache as well. I checked my phpinfo() after that but couldn't find php-mbstring there. I am still getting the same issue. Any help?
