How can the error related to the unexpected '}' in the PHP code be prevented through proper indentation and code structure?

To prevent the error related to the unexpected '}', proper indentation and code structure should be followed. Each opening brace '{' should have a corresponding closing brace '}' at the same indentation level. This helps in easily identifying matching pairs and prevents errors like unexpected '}'.

// Incorrect code with unexpected '}'
if ($condition) {
    echo "Condition is true";
}
else {
    echo "Condition is false";
}

// Corrected code with proper indentation
if ($condition) {
    echo "Condition is true";
} else {
    echo "Condition is false";
}
