return $n % 2 == 0;
});print_r($even);🔹 Q10 Solution
$numbers = [1, 2, 3, 4];$square = array_map(function($n) {
return $n * $n;
}, $numbers);print_r($square);🚀 ✅ Bonus Solution
🔹 Q11 Solution (Search System)
$names = ["Aditya", "Rahul", "Neha", "Amit", "Priya"];$search = "Rahul"; // You can take user input hereif (in_array($search, $names)) {
echo "Name found!";
} else {
echo "Name not found!";
}🎯 Extra Improvement (Advanced Version)
👉 With user input:
$names = ["Aditya", "Rahul", "Neha", "Amit", "Priya"];$search = $_GET['name'];if (in_array($search, $names)) {
echo "Name found!";
} else {
echo "Name not found!";
}
