How can PHP be utilized to handle complex conditional statements for age group filtering that MySQL syntax may struggle with?

PHP can be utilized to handle complex conditional statements for age group filtering by using logical operators such as && (AND) and || (OR) along with comparison operators like < (less than) and >= (greater than or equal to). This allows for more flexibility in defining age ranges and conditions that MySQL syntax may struggle with. By incorporating these conditional statements within PHP code, you can efficiently filter and retrieve data based on specific age groups.

// Example PHP code for age group filtering
$age = 30;

if ($age < 18) {
    echo "Age group: Under 18";
} elseif ($age >= 18 && $age < 30) {
    echo "Age group: 18-29";
} elseif ($age >= 30 && $age < 40) {
    echo "Age group: 30-39";
} else {
    echo "Age group: 40+";
}
