How can PHP developers handle outputting data from arrays with potentially missing fields to avoid empty spaces in the output?

When outputting data from arrays with potentially missing fields, PHP developers can use conditional statements to check if the field exists before outputting it. This can help avoid empty spaces in the output by only displaying the field if it is present in the array. 

$data = [
    'name' => 'John Doe',
    'age' => 30,
    // 'email' => 'john.doe@example.com', // Uncomment this line to simulate a missing field
];

if (isset($data['name'])) {
    echo 'Name: ' . $data['name'] . '<br>';
}

if (isset($data['age'])) {
    echo 'Age: ' . $data['age'] . '<br>';
}

if (isset($data['email'])) {
    echo 'Email: ' . $data['email'] . '<br>';
}
