What is the best practice for accessing specific values from a multidimensional array in PHP?

When accessing specific values from a multidimensional array in PHP, it is best practice to use multiple square brackets to navigate through the nested arrays. Each set of square brackets represents a level of depth in the multidimensional array. By specifying the key for each level, you can access the desired value. 

// Example of accessing a specific value from a multidimensional array
$multiArray = array(
    "first" => array(
        "name" => "John",
        "age" => 30
    ),
    "second" => array(
        "name" => "Jane",
        "age" => 25
    )
);

// Accessing the value "Jane" from the multidimensional array
$name = $multiArray["second"]["name"];
echo $name; // Output: Jane
