How can PHP developers avoid the error message related to 'void' in their code?

PHP developers can avoid the error message related to 'void' by ensuring that functions do not declare a return type of 'void' in their function definition. If a function does not return a value, it should not have a return type declared. Removing the 'void' return type from the function definition will prevent the error message from occurring. 

// Incorrect function declaration with 'void' return type causing error
function exampleFunction(): void {
    // Function logic here
}

// Correct function declaration without 'void' return type
function exampleFunction() {
    // Function logic here
}
