What are the best practices for accessing and displaying object key names in PHP?

When accessing and displaying object key names in PHP, it's important to handle cases where the key may not exist to prevent errors. One way to do this is by using the isset() function to check if the key exists before trying to access it. Additionally, you can use a loop to iterate over all the keys in the object and display them dynamically. 

// Example code snippet demonstrating best practices for accessing and displaying object key names in PHP

// Sample object
$object = (object) [
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3'
];

// Check if key exists before accessing it
if (isset($object->key1)) {
    echo "Key name: key1\n";
}

// Loop through all keys in the object and display them
foreach ($object as $key => $value) {
    echo "Key name: $key\n";
}
