MySQL behaviour you should be aware of

I've used MySQL over the years and it has served me well. I didn't know the default behaviour is a bit messed up. Look at this video for some examples:

Because there's a lot of validation being done by the php-applications I work on, I've yet to run into the problems described above.Though the default configuration has some problems I'm not migrating my current projects from MySQL to something else. But for fresh new projects, I'll consider using PostgreSQL.

If you are considering this as well here's a guide by Chris Fidao (I stumbled upon the video above when reading that guide). If you are in any way interested in running your own server you have to subscribe to his excellent newsletter, Servers for Hackers, and buy the book with the same name.

Functional programming in PHP

Almost a year ago Igor Wiedler wrote three articles on his blog about the state of functional programming in PHP.

The first article explores iteration. You'll learn to turn this


$admins = [];
foreach ($users as $user) {
    if (is_admin($user)) {
        $admins[] = $user;
    }
}

into this


use function iter\filter;
$admins = filter('project\user\is_admin', $users);

In the second one he explains a very nice way to traverse an associative array. How you currently do it:


$baz = (isset($data['foo']['bar']['baz'])) ? $data['foo']['bar']['baz'] : null;

How you'll do it in the future:


use function igorw\get_in;
$baz = get_in($data, ['foo', 'bar', 'baz']);

The final article shows you a nice syntax to handle objects that return null-values.

All the articles mention libraries that you can use in your code today.

Inside Composer's speed boost

If you've been following the news, you'll have noticed that yesterday Composer got a bit of a speed boost. And by "bit of a speed boost", we're talking between 50% and 90% reduction in runtime depending on the complexity of the dependencies. But how did the fix work? And should you make the same sort of change to your projects? For those of you who want the TL/DR answer: the answer is no you shouldn't.
