How can PHP beginners avoid writing code that may be considered "sinnfrei" or nonsensical?

PHP beginners can avoid writing nonsensical code by following best practices, such as using meaningful variable names, commenting their code, and organizing their code structure. They should also avoid unnecessary complexity and focus on writing clean and readable code. 

// Example of clean and readable code
$firstName = "John";
$lastName = "Doe";

// Concatenating variables
$fullName = $firstName . " " . $lastName;

echo "Hello, " . $fullName;
