What are common errors that can occur when trying to delete elements from a PHP script?

Common errors that can occur when trying to delete elements from a PHP script include using the wrong array key or index, not properly checking if the element exists before attempting to delete it, and not updating the array keys or indexes after deletion. To avoid these errors, always verify that the element exists in the array before attempting to delete it, and make sure to re-index the array if needed after deletion. 

// Example code snippet to safely delete an element from an array
$myArray = array("apple", "banana", "cherry");

// Check if the element exists before deleting
if (($key = array_search("banana", $myArray)) !== false) {
    unset($myArray[$key]);
}

// Re-index the array if needed
$myArray = array_values($myArray);

// Output the updated array
print_r($myArray);
