PHP arrived at a time when most server-side development was either being done through Perl. CGI ruled the day, and programming for the web wasn’t really that much fun. PHP was cobbled together to get things done quickly, and at the time, it opened up writing simple web applications to nearly everyone with a text editor. With a few tags, you could add a site counter, or call out to a database. ASP came soon after, but it was yucky, closed, Windows only. PHP was (and is) free and open for anyone to improve.
Pretty much every PHP developer writes comments along with the actual code. But the language itself doesn’t impose any rules on how to do so. You just have to wrap them around some specific tags and then you can write any content you want. So what exactly should be put in the comment blocks to keep them useful? Which parts of the code should be documented and which shouldn’t? In this article I will present some important rules which may help you in keeping your PHP code well documented and understandable.
When we look back on decisions, on architecture, it’s always easy to find the way we could have done better. How could the me of 6 months ago have written something so monstrously bad! But that’s just it, we always know more, are always growing, and we find ourselves equipped with new tools for understanding the world around us, and analyzing our choices. But that doesn’t invalidate the beauty of people doing the best they can with what they have. That’s the real beauty of PHP.. it’s the beauty of effort, of trying something, and, for better or worse, something which still profoundly affects us today.
Whats new in PHP 7?
As of PHP 7, the scalar types (integers, floating point numbers, booleans and strings) can also be used as type hints. Anyone accustomed to PHP 5 will notice the steep improvements made for PHP 7. Nonetheless, HHVM WordPress sites consume fewer CPU resources, which allows for more transactions per second for a high number of concurrent requests. Appserver only comes with PHP5.6 currently; version 1.2.0 will be arriving with PHP7 some time towards the middle to end of this year. As PHP 7.1 and onward develop, we will keep adding the new PHP features into HHVM, to continue having parity with the language.
I’m happy with this PHP 7 feature, because it allows developers to ensure a better input consistency of a function/method interface. By default coercive mode” is enabled. This restricts PHP from throwing a type error when the types don’t exactly match, but when a conversion is still possible.
By using PHP 7 not only your code will be executed faster but you will also need fewer servers to serve the same amount of users. You can install Tideways PHP Extension in various ways, it is not necessary to have an account for the Tideways product. This works fine, but there is a better option and that is PHP 7.0 Released in 2015, PHP 7.0 is a radical jump forwards for PHP in terms of performance, language features and reduction in memory usage. Since your server is running Debian 7 you won’t be seeing PHP 7 on your Cloud Console.
Software programming is a balanced mix of art (sometimes a euphemism for improvisation) and a bunch of well-proven heuristics used to tackle certain problems and solve them in a decent fashion. Few will disagree that the artistic side is by far the hardest one to polish and distill over time. On the other hand, taming the forces behind the heuristics is fundamental for being able to developing software that rests on the foundation of good design.
With so many developers stating how and why software systems should adobt a specific approach, it’s pretty disappointing not seeing a broader implementation of them in the world of PHP. PHP opened a lot of doors for people who wanted to get their first taste coding. While it’s easy to scorn PHP for being ugly, and poorly planned out, it serves in many ways as a high school sweetheart. Our first taste of intimacy and love, PHP offered many their first chance at writing more sophisticated web pages that were alive, not merely content. And you know, a lot of those same people who first got their start in PHP grew out of it, and good for them. But I think I’d rather look back on what PHP did for the world then, and how it continues to power many of the most popular sites on the internet.
