How can PHP developers optimize their code formatting and indentation to make it easier to debug and maintain?

PHP developers can optimize their code formatting and indentation by following a consistent coding style guide, such as PSR-1 and PSR-2. This helps make the code more readable, easier to debug, and maintain in the long run. Using proper indentation, spacing, and line breaks can also improve the overall organization of the code.

<?php

// Bad code formatting
function badFormattedCode(){
echo "This is badly formatted code";
}

// Good code formatting
function goodFormattedCode() {
    echo "This is well-formatted code";
}

?>
