How can PHP developers properly structure conditional statements to avoid missing closing brackets and causing errors?

To avoid missing closing brackets and causing errors in conditional statements, PHP developers can use proper indentation and formatting to clearly see the opening and closing brackets. Additionally, they can use code editors with syntax highlighting to visually identify matching brackets. Finally, developers can also break down complex conditional statements into smaller, more manageable chunks to reduce the likelihood of missing closing brackets.

if ($condition1) {
    // code block for condition 1
} elseif ($condition2) {
    // code block for condition 2
} else {
    // default code block
}
