• 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:
