• OOP in PHP 4 and 8

  Oct 2, 2020

  Deprecation of class name constructors means that you no longer can write OOP code that works both in PHP 4 and PHP 8 without some hackery. This works however:

  <?php
  
  class WorksIn4And8
  {
      var $int;
  
      // Regular method in PHP 4
      // Constructor in 5-8
      function __construct($int)
      {
          error_log('__construct()');
          $this->int = $int;
      }
  
      // Constructor in PHP 4
      // Constructor overridden by __construct in 5-7
      // Regular method in PHP 8
      function WorksIn4And8($int)
      {
          error_log('WorksIn4And8()');
          $this->__construct($int);
      }
  
      function getInt()
      {
          return $this->int;
      }
  }
  
  $obj = new WorksIn4And8(48);
  
  var_dump($obj->getInt());

• PHP 8.0 Syntax Showcase

  Sep 30, 2020

  Since RC1 is released today, I decided to make a small demonstration of PHP 8.0 syntax features.

  <?php
  
  #[FuncAttribute]
  function func(SplHeap|ArrayObject|null $object, mixed $value = null): ArrayAccess|false
  {
      return match ($object?->count()) {
          0, null => throw new RuntimeException(),
          default => $object,
      };
  }
  
  try {
      func(object: new ArrayObject());
  } catch (RuntimeException) {
      // ignore
  }

• OTP Links

  Aug 26, 2020

  Have you ever seen an one time password link in a regular <a> tag?

  Here is an example TOTP link from Google Authenticator repo:

  otpauth://totp/Example:[email protected]?secret=JBSWY3DPEHPK3PXP&issuer=Example

  The most familiar form for them is QR codes:

  

  Which is a problem if you're alterady on your mobile device and you can't scan it. For this case there is usually a text like "Please manually add the key JBSW Y3DP EHPK 3PXP to your Authenticator app". But what about the link itself? Well, just try it on your phone: click me.

  I'm really shocked that it works perfectly and that I have never seen this simple and very web style solution in action.

• Method Calls with Arbitrary Names

  Jul 24, 2020

  A discovery of the day. Many people know that you can define and read an object property with an arbitrary name:

  <?php
  
  $s = new stdClass();
  $s->{'any string here'} = 123;
  echo $s->{'any string here'}; // 123

• Kernel#send Should Be Removed

  Jul 24, 2020

  Opinion: Kernel#send should be deprecated and removed from future rubies.

  send always felt weird when I was an active ruby developer but I have never seen any strong criticisms on it. It's either an attack on all family of send-like calls or a fierce defence that "using send is not a bad practice". Only some style guides argue against send because it may overlap with existing methods. This post was written after reading one of defences.

• I released the first PHP 8 library ever

  Jul 3, 2020

  At least among the libraries listed on the Packagist. On this Tuesday sandfoxme/bencode was updated to 2.0 that requires PHP 8 as a minimum. While it was meant mostly as an experiment and a joke, it allowed me to try some new features like Stringable interface and remove some old compatibility handling thanks to mbstring.func_overload being finally removed.

• sabre/xml

  Jun 10, 2020

  An awesome discovery of today was made in an article titled An XML library for PHP you may not hate. As an unexpected twist I really didn't hate it, in fact it helped me to solve a problem that I had. It is called sabre/xml and it's a part of the sabre/dav project.

• What's Wrong with StrictYAML

  May 29, 2020

  While I'm still delaying my position on TOML vs YAML holy war let's look at the StrictYAML.

  StrictYAML is a type-safe YAML parser that parses and validates a restricted subset of the YAML specification.

  Seems great but let's look at the removed features list, Implicit Typing to be precise:
