How can PHP developers handle complex query string structures with multiple operators and values while maintaining code readability and efficiency?

Handling complex query string structures with multiple operators and values can be challenging, but using PHP's built-in functions like `parse_str` can help parse the query string into an array for easier manipulation. To maintain code readability and efficiency, consider breaking down the query string into smaller, more manageable parts, and using conditional statements or loops to handle different operators and values efficiently. 

$queryString = "name=John&age>30&city=New York&salary<=50000";

parse_str($queryString, $params);

foreach ($params as $key => $value) {
    // Handle different operators and values here
    // For example, you can use if-else statements to check for operators like >, <, =, etc.
    // Perform necessary operations based on the values
}
