What is the best practice for looping through objects in PHP, and what are the potential pitfalls to avoid?

When looping through objects in PHP, the best practice is to use the `foreach` loop to iterate over the object properties. This allows you to access each property without needing to know the object's structure in advance. However, it's important to check if the object is iterable before attempting to loop through it to avoid errors. 

// Check if the object is iterable before looping through it
if(is_iterable($object)) {
    foreach($object as $key => $value) {
        // Access object properties using $key and $value
        echo $key . ': ' . $value . '<br>';
    }
} else {
    echo 'Object is not iterable';
}
