What are common issues when working with arrays in PHP?

Issue: One common issue when working with arrays in PHP is trying to access an element that doesn't exist, which can result in errors or unexpected behavior. To avoid this issue, you can check if the element exists before trying to access it using functions like isset() or array_key_exists(). 

// Check if the element exists before accessing it
if (isset($array['key'])) {
    $value = $array['key'];
    // Do something with $value
} else {
    // Element doesn't exist
    echo "Element 'key' does not exist in the array";
}
