How can PHP developers ensure code readability when dealing with complex loops and conditional statements in arrays?

To ensure code readability when dealing with complex loops and conditional statements in arrays, PHP developers can use meaningful variable names, properly indent their code, and add comments to explain the logic behind the loops and conditions. Breaking down complex logic into smaller, more manageable functions can also help improve code readability. 

// Example of using meaningful variable names, proper indentation, and comments for readability
$users = [
    ['name' => 'John', 'age' => 30],
    ['name' => 'Jane', 'age' => 25],
    ['name' => 'Bob', 'age' => 35],
];

// Loop through the users array and check if the user is older than 30
foreach ($users as $user) {
    if ($user['age'] > 30) {
        echo $user['name'] . ' is older than 30.';
    } else {
        echo $user['name'] . ' is 30 or younger.';
    }
}
