What are the potential pitfalls of using the shorthand method of accessing array values in PHP?

Potential pitfalls of using the shorthand method of accessing array values in PHP include decreased code readability and potential for errors if the array key does not exist. To solve this issue, it is recommended to use the isset() function to check if the array key exists before attempting to access it. 

// Using isset() to check if array key exists before accessing it
$array = ['key' => 'value'];

if(isset($array['key'])){
    $value = $array['key'];
    echo $value;
} else {
    echo "Key does not exist";
}
