How can beginners avoid pitfalls when coding PHP functions, such as properly declaring variables with a $ sign?

Beginners can avoid pitfalls when coding PHP functions by ensuring that they properly declare variables with a `$` sign. This symbol is crucial for indicating that a variable is being declared or used within the code. Failing to include the `$` sign can result in syntax errors or unexpected behavior in the program. By consistently using the `$` sign before variable names, beginners can write cleaner and more error-free PHP code. 

// Incorrect way of declaring a variable without the $ sign
name = "John Doe";

// Correct way of declaring a variable with the $ sign
$name = "John Doe";
