What are some common pitfalls to avoid when dealing with nested arrays in PHP and trying to update specific values?

When dealing with nested arrays in PHP and trying to update specific values, a common pitfall to avoid is not correctly accessing the nested arrays using the correct keys. To solve this issue, you should make sure to navigate through the nested arrays using the appropriate keys to reach the specific value you want to update. 

// Example nested array
$data = [
    'users' => [
        ['name' => 'John', 'age' => 30],
        ['name' => 'Jane', 'age' => 25]
    ]
];

// Update the age of the second user
$data['users'][1]['age'] = 26;

// Print updated data
print_r($data);
