An associative array uses named keys instead of numeric indexes. Useful for key-value mappings.
Quick Answer
Associative array uses string keys instead of numeric indexes. $user = ["name" => "Alice", "age" => 25]. Access: $user["name"]. Add: $user["email"] = "alice@example.com". Remove: unset($user["age"]). Check key exists: array_key_exists("name", $user) or isset($user["name"]). Iterate: foreach($user as $key => $value). Like a dictionary/hash map in other languages.
