What are the best practices for handling non-existent array elements in PHP to avoid Notice messages?

When accessing array elements in PHP that may not exist, it's important to check if the element exists before trying to access it to avoid Notice messages. This can be done using functions like isset() or array_key_exists() to ensure the element is present before accessing it. By implementing these checks, you can prevent PHP from throwing notices about undefined array elements. 

// Check if the array element exists before accessing it
if(isset($array['key'])){
    // Access the array element if it exists
    $value = $array['key'];
    // Use the $value variable as needed
}
