How can PHP developers effectively troubleshoot issues related to accessing specific array elements?

To effectively troubleshoot issues related to accessing specific array elements in PHP, developers can use functions like isset() or array_key_exists() to check if the desired key exists in the array before accessing it. Additionally, they can use var_dump() or print_r() functions to inspect the array structure and contents for debugging purposes. 

// Example code snippet to demonstrate troubleshooting accessing specific array elements
$array = ['key1' => 'value1', 'key2' => 'value2'];

// Check if key exists before accessing it
if (isset($array['key1'])) {
    echo $array['key1'];
} else {
    echo 'Key does not exist in the array';
}

// Using var_dump() to inspect array structure and contents
var_dump($array);
