What are the best practices for iterating through an array generated by the explode function in PHP?

When iterating through an array generated by the explode function in PHP, it's important to first check if the array is not empty to avoid errors. Then, you can loop through the array using a foreach loop to access each element individually. 

// Example code for iterating through an array generated by explode function
$string = "apple,banana,orange";
$array = explode(",", $string);

if (!empty($array)) {
    foreach ($array as $item) {
        echo $item . "<br>";
    }
}
