What are some common pitfalls when trying to delete values from an array in PHP?

One common pitfall when trying to delete values from an array in PHP is not adjusting the array keys after removal, which can lead to unexpected behavior when accessing the array later on. To solve this, you can use the `unset()` function to remove the desired element from the array and then use `array_values()` to reindex the array keys. 

// Example array
$fruits = array("apple", "banana", "cherry", "date");

// Remove "banana" from the array
unset($fruits[1]);

// Reindex the array keys
$fruits = array_values($fruits);

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