What are the best practices for handling errors and exceptions when working with PHP functions that return arrays?

When working with PHP functions that return arrays, it is important to handle errors and exceptions gracefully to prevent unexpected behavior or crashes in your application. One best practice is to check if the function returned a valid array before attempting to access its elements. This can be done using functions like `is_array()` or `empty()` to ensure the array is not empty or null before proceeding with any operations. 

// Example code snippet demonstrating error handling when working with functions that return arrays

// Call a function that returns an array
$result = someFunction();

// Check if the result is a valid array before proceeding
if (is_array($result) && !empty($result)) {
    // Access and process the elements of the array
    foreach ($result as $item) {
        echo $item . "<br>";
    }
} else {
    // Handle the case where the function did not return a valid array
    echo "Error: Invalid array returned from function";
}
