How can associative arrays be effectively utilized in PHP to address database entries?

Associative arrays can be effectively utilized in PHP to address database entries by storing database query results in a structured manner. This allows for easy access to specific data fields using keys, making it simpler to manipulate and display database information in PHP scripts. 

// Example of utilizing associative arrays for database entries
$query = "SELECT * FROM users";
$result = mysqli_query($connection, $query);

$users = array();
while ($row = mysqli_fetch_assoc($result)) {
    $users[$row['id']] = $row;
}

// Accessing specific user information
$userID = 1;
echo "User ID: " . $users[$userID]['id'] . "<br>";
echo "Username: " . $users[$userID]['username'] . "<br>";
echo "Email: " . $users[$userID]['email'] . "<br>";
