What are some best practices for accessing nested arrays in PHP?

When accessing nested arrays in PHP, it is important to use the correct syntax to navigate through the nested levels. One common approach is to use multiple square brackets to access the desired element within the nested arrays. It is also helpful to use conditional statements or loops to handle cases where the nested arrays may vary in depth. 

// Example of accessing a nested array in PHP
$data = [
    'first_level' => [
        'second_level' => [
            'third_level' => 'value'
        ]
    ]
];

// Accessing the 'third_level' value
$third_level_value = $data['first_level']['second_level']['third_level'];
echo $third_level_value; // Output: value
