What are best practices for handling arrays in PHP for website redirection purposes?

When handling arrays in PHP for website redirection purposes, it is best practice to check if the array key exists before accessing it to avoid errors. Additionally, using the header() function to perform the redirection is recommended for a seamless transition to the new page. 

// Check if the array key exists before accessing it
if(isset($redirectArray['url'])) {
    // Perform the redirection using the header() function
    header("Location: " . $redirectArray['url']);
    exit();
}
