Adding a New Event

Part of the Logic & Flow section of Coddy's PHP journey — lesson 60 of 68.

Challenge

Easy

You will receive two inputs: a JSON string representing the existing events array from the previous lesson, and three values on the second line separated by spaces representing a new event's name, date, and location.

The first input will be a JSON string in this format: [{"name":"Team Meeting","date":"2024-04-15","location":"Office"},{"name":"Conference","date":"2024-05-20","location":"Convention Center"}]

The second input will be three space-separated values in this format: Workshop 2024-06-10 Library

Read both inputs. Decode the JSON string into an events array. Then, parse the second input to extract the event name, date, and location. Create a new associative array for this event with keys "name", "date", and "location", and add it to the events array using array_push().

After adding the new event, iterate through all events in the array and print each one in the following format:

Event: [name] on [date] at [location]

Print each event on a separate line, in the order they appear in the array.

Input format:

First line: A JSON string representing the existing events array
Second line: Three space-separated values representing the new event's name, date, and location (example: Workshop 2024-06-10 Library)

Expected output: Each event (including the newly added one) printed on a separate line in the format: Event: [name] on [date] at [location]

Try it yourself

<?php
// Read the JSON string from the first input
$jsonInput = trim(fgets(STDIN));

// Read the new event details from the second input
$newEventInput = trim(fgets(STDIN));

// Decode the JSON string into an array
$events = (array)json_decode($jsonInput, true);

// Parse the new event details (name, date, location)
list($name, $date, $location) = explode(' ', $newEventInput);

// TODO: Write your code below
// Create a new event array and add it to the events array using array_push()
// Then iterate through all events and print them in the required format

?>
