To get the first character of a string, we can use the built-in
substr() function by passing
0,1 as second and third arguments in PHP.
Syntax : substr(string, start, length)
Here is an example, that gets the first character
H from the following string.
<?php echo substr("Hello",0,1); ?>
Similarly, we can also use the mb_strimwidth() function in php.
<?php echo mb_strimwidth("Cake",0,1); ?>
To use the
mb_stringwidth() function you need to install a
php-mbstring package using the following command and restart the apache.
sudo apt-get install php7.0-mbstring
