Example of deleting elements from php array_PHP tutorial

Let’s give an example:

I previously imagined that after unset, the array $arr should compress the array to fill in the missing element positions, but after print_r($arr), the result is not like that. The final result is Array ( [0] => a [2] => c [3] => d );

$arr = array('a','b','c','d');

print_r($arr) ; // Array ( [0] => a [1] => c [2] => d )< /span> 
?>
