PHP 7.4 releases with type declarations, shorthand syntax in Arrow functions, and more!

In the month of April, the PHP development team announced the availability of PHP version 7.4. This marks the fourth feature update to the PHP 7 series. PHP 7.4 comes with numerous improvements and new features.

Key features in PHP 7.4

  • Class properties support type declarations.
  • Starting from PHP 7.4, arrow functions will provide a shorthand syntax for defining functions with implicit by-value scope binding
  • The full variance support is only available if autoloading is used by the user. Also, a single file will now only support non-cyclic type references.
  • Numeric literals can contain underscores between digits.
  • Weak references in PHP 7.4 will allow the programmers to retain a reference to an object that does not prevent the object from being destroyed.
  • Users can now throw exceptions from __toString(). This was previously not permitted in PHP as it used to result in a fatal error.
  • The CURLFile now supports stream wrappers in addition to plain file names.
  • The FILTER_VALIDATE_FLOAT filter will support the min_range and max_range options, with the same semantics as FILTER_VALIDATE_INT.
  • A new FFI extension is introduced. It will provide a simple way to call native functions, access native variables, and create/access data structures defined in C libraries.
  • A new IMG_FILTER_SCATTER image filter is added to introduce a scatter filter to images.
We are happy with the new features in PHP 7.4 release.

Making open source JavaScript pay

Image
Money isn’t everything to the success of the most popular JavaScript frameworks. Or is it? Looking at the  2019 State of JavaScript report , something stands out: Money apparently can’t buy everything. Or, at least, not every major front-end and back-end programming framework is sponsored by a big company. Sure, we have Google to thank for  Angular , and Facebook gets credit for  React , but what about  Vue.js ? Or Gatsby? Or Next.js? While these (and other) open source projects do seem to suggest a future without Big Corps shoveling Big Money into open source, the reality is a bit more nuanced. For the developers looking to pay their way through open source, however, reality isn’t nuanced at all. For every Vue.js founder  Evan You making $16,000 per month with Patreon contributions , there are thousands of developers struggling to scrape together $16 for the important open source work they’re doing.

How artificial intelligence is making the education system more relevant?

Image
Digital learning solutions equipped with artificial intelligence are making revolutionary changes to the way education is imparted in students with varied interests and capabilities. When we think of artificial intelligence, there is a hardwired imagery of gigantic thinking machines working in sci-fi environment. This imagery often comes from the science fiction that we have been watching or reading since childhood. However, deep diving suggests that artificial intelligence is an advanced form of algorithm that empowers machines to emulate human behavior under real life situations. Today, there is no industry untouched by the ripples caused by artificial intelligence. Education sets the foundation of human behavior. Educational ecosystem is formed by knowledge base, teaching skills and experience, learning capability, and evolving teaching methods. Digital learning solutions equipped with artificial intelligence are making revolutionary changes to the way educat...

What Is Brutalism in Web Design?

Image
3   min read   Brutalism is a special breed of web design, working well for quirky, creative brands and individuals. However, this rule-bending design technique must be employed with care. Read this guide to find out how. Brutalism is one of those trends that seems to come and go in web design. It’s not because there isn’t much value in brutalist design. It’s more that it doesn’t always fit with the style and tone of the times.  That’s part of what makes brutalism so intriguing though. When most websites tend to fall in line and adopt the same basic trends from year to year, a website that doesn’t play by the rules can easily steal the spotlight.  You just need to know whether that’s the right kind of light you want to shine on the brand. Brutalism can sometimes come off as cold and somber. If it’s not properly executed or not used for the right kind of brand, it can send the wrong signals to website visitors.  In this guide to brutalism in web design, we’l...
