How can PHP developers effectively nest if conditions to avoid errors and improve code readability?

To effectively nest if conditions in PHP, developers should use proper indentation and structure their code in a logical manner to avoid errors and improve readability. By organizing nested conditions with clear spacing and indentation, it becomes easier to follow the flow of logic and identify any potential issues. Additionally, utilizing elseif statements can help streamline nested conditions and make the code more concise. 

// Example of nesting if conditions with proper indentation and elseif statements
$grade = 85;

if ($grade >= 90) {
    echo "A";
} elseif ($grade >= 80) {
    echo "B";
} elseif ($grade >= 70) {
    echo "C";
} elseif ($grade >= 60) {
    echo "D";
} else {
    echo "F";
}
