Are there any potential pitfalls when using PHP foreach loop with arrays of objects?

When using a PHP foreach loop with arrays of objects, it's important to check if the array is empty before iterating over it to prevent errors. If the array is empty, attempting to loop through it with foreach will result in a warning or error. To avoid this, you can use the empty() function to check if the array is empty before using the foreach loop. 

// Check if the array is not empty before using foreach loop
if (!empty($arrayOfObjects)) {
    foreach ($arrayOfObjects as $object) {
        // Do something with each object
    }
}
