Removing a Task

Part of the Fundamentals section of Coddy's PHP journey — lesson 58 of 71.

Challenge

Easy

In the previous lesson, you marked a task as complete. Now, add the ability to remove a task from the list entirely.

Read four lines of input for task descriptions (three initial tasks plus one new task). Then read a fifth input: an integer representing the index of the task to mark as complete. Finally, read a sixth input: an integer representing the index of the task to remove from the list.

After building the $todos array with all four tasks and marking the specified task as complete, remove the task at the given removal index using array_splice().

The array_splice() function removes elements from an array:

<?php
array_splice($array, $index, 1); // Removes 1 element at $index
?>

Then loop through the remaining tasks and print each one in the same format as before:

If the task is completed: - [task description] (Done)
If the task is pending: - [task description] (Pending)

Print each task on a separate line.

Example:

If the inputs are Buy groceries, Walk the dog, Finish homework, Call mom, 1, and 2, the output should be:

- Buy groceries (Pending)
- Walk the dog (Done)
- Call mom (Pending)

If the inputs are Clean room, Read book, Exercise, Cook dinner, 0, and 0, the output should be:

- Read book (Pending)
- Exercise (Pending)
- Cook dinner (Pending)

Try it yourself

<?php
// Read three task descriptions
$task1 = trim(fgets(STDIN));
$task2 = trim(fgets(STDIN));
$task3 = trim(fgets(STDIN));

// Read the new task to add
$newTask = trim(fgets(STDIN));

// Read the index of the task to mark as complete
$completeIndex = (int)trim(fgets(STDIN));

// Create a $todos array containing three task arrays
// Each task should be an associative array with "task" and "completed" keys
$todos = [
    ["task" => $task1, "completed" => false],
    ["task" => $task2, "completed" => false],
    ["task" => $task3, "completed" => false]
];

// Add the new task to the end of the array
$todos[] = ["task" => $newTask, "completed" => false];

// Mark the task at the specified index as complete
$todos[$completeIndex]["completed"] = true;

// Loop through the array and print each task in the formatted list
foreach ($todos as $todo) {
    if ($todo["completed"]) {
        echo "- " . $todo["task"] . " (Done)\n";
    } else {
        echo "- " . $todo["task"] . " (Pending)\n";
    }
}
?>
