What are common issues with arrays in PHP and how can they be resolved?

Issue: Accessing an element in an array that does not exist can result in a "Undefined offset" notice. Solution: To avoid this notice, you can first check if the element exists using the isset() function before trying to access it. 

$array = [1, 2, 3, 4];

if(isset($array[5])) {
    // Element exists, do something with it
    echo $array[5];
} else {
    // Element does not exist
    echo "Element does not exist";
}
