Laravel Vapor, which is a first-party serverless platform for Laravel applications running on AWS, has some really impressive numbers. Without PHP, I don’t know what I’d be doing now. There are plenty of frameworks and packages to choose from if that’s the way you’d like to go. In PHP 7 (phpng), is_null is actually marginally faster than ===, although the performance difference between the two is far smaller. Python is highly regarded as beginner friendly, yet doesn’t get the same “dangerous” reputation. PHP（ピー・エイチ・ピー）は "The PHP Group" によってコミュニティベースで開発 [2] されているオープンソースの汎用プログラミング言語およびその公式の処理系であり、特にサーバーサイドで動的なウェブページを作成するための機能を多く備えていることを特徴とする [3]。 Learning a language isn’t actually that hard and an experienced programmer might be able to pick up the gist of a language in a weekend. It’s because of the existance of the Java EE Platform. I love that PHP is easy to get started with, but I also love that it’s complex and there’s actually so much to know to be considered a professional PHP programmer. It doesn’t mean I won’t use Python at all, or that I have anything against Python, it just means that PHP is my go-to. What you're seeing is not Photoshopped. In truth, PHP is able scale just fine, if you write decent code. The thing is that it’s still not that simple and I think a lot of the misconception comes from WordPress, which, until recently was well known for having scalability issues. With the recent release of PHP 8, “now” felt like the right time. Just a side note, some time ago I was a part of a small team which built and deployed an events management platform onto the internal network of one of South Africa’s foremost financial institutions (I might write something about my experiences with that).

As the old adage goes: time is money, and in most cases, taking on a new language for a project is a big undertaking that would put more strain on timeframes which are usually already tight. Saving microseconds on a lot of "simple" operations in the entire PHP execution chain usually results in being able to serve more pages per second at the same speed, or lowering your cpu usage. Sure, not really with WordPress anymore, and I like to think I’ve matured as a PHP programmer to know how to write this post. For example, PHP probably isn’t your first choice if you’re working in the machine learning space (although there are some very interesting projects that are showing some promise). These things are more than just “knowing” a language. it’s just way outside of its wheelhouse. $var===NULL is much faster than is_null($var) (with the same result). Regular errors should be logged on the server using the default PHP logging system. Newer versions of PHP, in the right environment and configured correctly, are more than capable of dealing with a large number of requests per second. Now PHP is showing 1004 and JS is showing me 1000 characters, Why? 20 years later, and I’m still building things in PHP. Those are just not going to be valuable comparisons. I’m self-taught, and I don’t have much in the way of formal training. The theory goes that if PHP is so easy, then it’s also really easy to write really dangerous code in PHP. In fact, it’s seriously frowned upon. Integer size can be determined from PHP_INT_SIZE, maximum value from PHP_INT_MAX since PHP 4.4.0 and PHP 5.0.5." I’ve been writing this for a while now.

However, if you can believe it, this “ease of use” is actually one of the complaints about PHP. And PHP 8 brings some really great tools to help make your code even more “beautiful”. Love it or hate it, WordPress is the reason we’re all here. PHP Assignment Operators The PHP assignment operators are used with numeric values to write a value to a variable. This is sometimes used to show that PHP is slow (or fast, in some cases). This is an actual photo of a real world, honest to God double-clawed hammer.Such a thing exists. Sounds kinda like a framework, right? There’s a lot wrong with WordPress and there’s a … It should have the file type CLI. Arguing against the use of PHP because it is ugly is just silly. Yes, Windows is far more complex than your average shopping cart website, but I think the argument stands. Although I’ll likely never use many of them professionally, I learnt so much about being a programmer just by learning another language. For many of the projects we’re involved in, that would be large. All us young kids that wanted a blog but didn’t have the knowledge to build them ourselves. I don’t truly remember when I started), among other languages, and, for the most part, I have simply ignored much of that side of the conversation.

If PHP really was dying, then sure, you’d have a reason to move on, but right now, in this moment, it isn’t dying. What makes a language “enterprise ready”? I love the fact that I can tell computers what to do and that I taught myself how to do that. If there’s one thing you take from this post, it should be: “learn another language”, but not because “php is dying” – It’s just not true. With each major release we get better and more useful tools.

From the validation rules table on the previous page, we see that the "Name", "E-mail", and "Gender" fields are required. The language itself, yes, but also it’s environment, what code it’s running, how the interpreter is configured, etc. I really don’t get where this comes from.

Look at this incredible thing Ian Baker created. This isn’t a “my language is better than your language” rant, and I honest believe that every programming language has a purpose. This was supposed to be about how PHP is not crap. This test is not for a Junior position, it's supposed to be a Senior PHP evaluation, so they are expecting that I will deliver some modern PHP code.
