To add items to an array in PHP, you can use several methods depending on the type of array (indexed or associative). Here are the common ways:

1. Add to Indexed Array

$fruits = ["apple", "banana"]; $fruits[] = "orange"; // Add at the end array_push($fruits, "grape", "melon"); // Add multiple items print_r($fruits);

2. Add to Associative Array

$user = [ "name" => "John", "age" => 30 ]; $user["email"] = "john@example.com"; // Add new key-value pair print_r($user);

3. Merge Arrays

$a = [1, 2]; $b = [3, 4]; $c = array_merge($a, $b); // Combine arrays print_r($c);

4. Using the + Operator (Preserves Keys)

$a = ["a" => 1]; $b = ["b" => 2]; $c = $a + $b; // $a values take precedence if keys overlap print_r($c);
