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
mb_substr()
is a multibyte-safe version of substr()
, meaning it works with characters as opposed to bytes. This is most noticeable in UTF-8, where many characters are represented by two or more bytes.
According to the installation instructions, mbstring
is not a built-in extension. You must enable it by having the appropriate files and configuring PHP correctly. Some information can be found in the link provided, your webhost should be able to help you with the rest.
To see if mbstring is installed:
php -m | grep mbstring
For Linux, install using
sudo apt-get install php-mbstring
Throw this into a terminal:
php -m | grep mb
If mbstring
shows up then it should work.
