How can defining constants in PHP help prevent errors and improve code readability, especially when dealing with string values like "Alle"?

Defining constants in PHP can help prevent errors and improve code readability by providing a single point of reference for important values like "Alle". By using constants, you can avoid typos and ensure consistency throughout your code. This can make it easier to update values in the future and understand the purpose of certain strings or variables. 

define('ALLE', 'Alle');

// Later in your code
echo ALLE;
