How to properly delete an element from an array in PHP? Problems with unset and reindexing

Hello everyone! I'm a beginner in PHP and encountered a problem when deleting elements from an array. I'm writing a simple script for managing a task list. I have an array with tasks, and I want to delete a task by its index. Here's my code: ```php $tasks = ['Buy milk', 'Do homework', 'Call a friend', 'Brush teeth']; // I want to delete the task with index 1 ('Do homework') unset($tasks[1]); print_r($tasks); ``` After executing unset, I get this output: ``` Array ( [0] => Buy milk [2] => Call a friend [3] => Brush teeth ) ``` Index 1 is gone, but the remaining indices are not reorganized! Now I have a gap in the array. When I try to access the element at index 1, I get an error. And if I want the array to be sequential (0, 1, 2), how do I do that?
