PHP String Length
The handling of strings is one of the pillars of PHP programming, and although there are countless functions to work with that can be consulted in the official programming, here we will only see the most used ones.

For example:
echo "\ x2a"; // display an asterisk using hex notation
$who = "María";
echo "Hello $who \ n"; // show Hello María and change lines
echo 'Hello $who \ n'; // show Hello María \ n
echo 'My name is...
