How does the unset() function work in PHP when removing entries from an array?

When using the unset() function in PHP to remove entries from an array, it works by deleting a specific key and its corresponding value from the array. This can be useful when you want to remove a specific element from an array without reindexing the keys. After using unset(), the key will no longer exist in the array. 

// Example of using unset() to remove an entry from an array
$fruits = array("apple", "banana", "orange", "kiwi");

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

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