What are some best practices for handling arrays in PHP templates to ensure all elements are displayed correctly?

When handling arrays in PHP templates, it's important to ensure that all elements are displayed correctly by properly iterating through the array and accessing each element. One common mistake is not checking if the array key exists before trying to access it, which can result in errors or missing data. To avoid this issue, use functions like `isset()` or `array_key_exists()` to verify the existence of the key before attempting to access it. 

// Example of iterating through an array and displaying all elements safely
$array = ['apple', 'banana', 'cherry'];

foreach ($array as $key => $value) {
    if (isset($array[$key])) {
        echo $array[$key] . "<br>";
    }
}
