How important is it to follow best practices and coding standards when writing PHP code?

Following best practices and coding standards is crucial when writing PHP code as it helps improve code readability, maintainability, and scalability. Adhering to these standards also ensures consistency across the codebase, making it easier for multiple developers to work on the same project. By following best practices, developers can reduce the likelihood of introducing bugs and errors in their code.

$firstName = 'John';
$lastName = 'Doe';

// Follow proper indentation and formatting
if ($firstName == 'John') {
    echo 'Hello, John!';
}

// Comment code to explain its purpose
// This function calculates the sum of two numbers
function calculateSum($num1, $num2) {
    return $num1 + $num2;
}
