PHP: Date
One of the main date functions in PHP is date(). It converts the timestamp to a human-readable format. The first parameter you need to pass to this function is the date format, which is arranged similarly to the formats for sprintf().
<?php
// Y means year
date('Y'); // 2018
date() uses the current time by default. But if necessary, you can pass it a specific timestamp.
<?php
date('M', 123123123); // Nov
There are dozens of different formatting options in the date() function. They're all listed in detail on the documentation page. It's not at all necessary to memorize them all, but it's useful to understand the general principle of how it should work. All options can be combined with each other in any variation.
<?php
date('l jS \of F Y h:i:s A'); // Thursday 26th of July 2018 10:58:55 AM
Instructions
Write an implementation of the getCustomDate() function that returns the date in the format 15/03/1985 based on the timestamp passed.
Call examples:
<?php
getCustomDate(1532435204); // 24/07/2018;
getCustomDate(532435204); // 15/11/1986;
getCustomDate(5324352); // 03/03/1970;
The exercise doesn't pass checking. What to do? 😶
If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:
- Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.
In my environment the code works, but not here 🤨
Tests are designed so that they test the solution in different ways and against different data. Often the solution works with one kind of input data but doesn't work with others. Check the «Tests» tab to figure this out, you can find hints at the error output.
My code is different from the teacher's one 🤔
It's fine. 🙆 One task in programming can be solved in many different ways. If your code passed all tests, it complies with the task conditions.
In some rare cases, the solution may be adjusted to the tests, but this can be seen immediately.
I've read the lessons but nothing is clear 🙄
It's hard to make educational materials that will suit everyone. We do our best but there is always something to improve. If you see a material that is not clear to you, describe the problem in “Discussions”. It will be great if you'll write unclear points in the question form. Usually, we need a few days for corrections.
By the way, you can participate in courses improvement. There is a link below to the lessons course code which you can edit right in your browser.
Your exercise will be checked with these tests:
1<?php

3namespace HexletBasics\Dates\DateFunction;

5use PHPUnit\Framework\TestCase;
6
7class Test extends TestCase
8{
9 public function test()
10 {
11 require 'index.php';
12
13 assert(getCustomDate(1532435204) === '24/07/2018');
14 assert(getCustomDate(532435204) === '15/11/1986');
15 assert(getCustomDate(5324352) === '03/03/1970');
16 }
17}
