What are the potential pitfalls of using multiple spaces in PHP code examples and how can they be addressed?

Using multiple spaces in PHP code can lead to inconsistent formatting and make the code harder to read and maintain. To address this issue, it is recommended to use a consistent number of spaces for indentation, typically four spaces, and avoid mixing spaces and tabs. Example fix: 

// Bad practice using multiple spaces for indentation
function exampleFunction() {
    $variable = 10;
      if ($variable > 5) {
          echo "Variable is greater than 5";
      }
}

// Good practice using consistent four spaces for indentation
function exampleFunction() {
    $variable = 10;
    if ($variable > 5) {
        echo "Variable is greater than 5";
    }
}
