What potential pitfalls can arise when trying to access specific values in an array in PHP?

One potential pitfall when trying to access specific values in an array in PHP is encountering "Undefined index" notices if the specified key does not exist in the array. To avoid this issue, you can use the isset() function to check if the key exists before trying to access it. 

// Check if the key exists before accessing it
if(isset($array['key'])){
    $value = $array['key'];
    // Use the value here
} else {
    // Handle the case where the key does not exist
}
