How can developers avoid common pitfalls when working with arrays and accessing their elements in PHP scripts?

One common pitfall when working with arrays in PHP is accessing elements that may not exist, leading to errors or unexpected behavior. To avoid this, developers should always check if an element exists before trying to access it. 

// Check if the element exists before accessing it
if(isset($array['key'])) {
    $value = $array['key'];
    // Proceed with using $value
} else {
    // Handle the case where the element doesn't exist
}
