What are some best practices for handling arrays in PHP to prevent errors like the one mentioned in the forum thread?

The issue mentioned in the forum thread likely involves accessing array elements without checking if they exist, leading to potential errors. To prevent this, it is best practice to always check if an array key exists before trying to access it to avoid errors. 

// Check if the array key exists before accessing it
if (isset($array['key'])) {
    // Access the array element
    $value = $array['key'];
} else {
    // Handle the case where the key does not exist
    $value = null;
}
