It should have the file type CLI. I love how it’s been improving over the last few years. Python is highly regarded as beginner friendly, yet doesn’t get the same “dangerous” reputation. I came to PHP like I believe most PHP programmers do. With each major release we get better and more useful tools. I come from a design background, and although I’ve been tinkering with computers and code since I was like 7 years old, I didn’t follow that passion in education. Regarding avoidance of NULLs in your MySQL queries, why not use IS NULL and IS NOT NULL in your WHERE clauses. Note: Make sure that your PHP folder has the php.exe. That’s why it’s really disappointing when another programmer, tells me my choice of language is “shit”. I live in a nice house and drive a great car because I spent 20 years getting really good at this one thing. Step 5: Configure PHP as an Apache module. Then you made your own theme. It’s not the language that makes code dangerous, it’s the lack of knowledge. It could be argued that WordPress was a reflection of the limitations of PHP, but that was a long time ago, and the language has matured extensively since then.

Although those numbers are very interesting I have a tendency to believe that they’re a bit misleading. Asking for help, clarification, or responding to other answers.

I sometimes think the question of scalability is also a bit of an over exaggeration. For almost all of those years, PHP has been “dying” and I should’ve stop using it years ago. It’s almost always already been done for you. The answer to that question is for a different post entirely.

I have really talented designer friends who also love what they do). I probably wouldn’t be writing my web applications in C++ (or at least it would be WAY down the list of languages for those projects), but that doesn’t make C++ a bad language. Laravel Vapor, which is a first-party serverless platform for Laravel applications running on AWS, has some really impressive numbers. PHP does not support unsigned integers.

PHP is as fast or as slow as the code you write. In fact, it’s seriously frowned upon. Is the suggestion then that languages which are harder to use are less likely to be used to create bad code? Human Language and Character Encoding Support. Knowing a programming language isn’t just about knowing which built-in function does what, it’s about having enough experience to know WHEN to use what features, or how the ecosystem fits together. I like computers, and I like the internet, but instead… I chose graphic design. In general, it's not normal. I love the language and the ecosystem. Field Validation Rules; Name: Required.

When people say that PHP doesn’t scale they usually referring to the idea that applications written in PHP might not be able to handle very large numbers of requests (like in the millions). I read somewhere that something like 70% of the patches that Microsoft release for Windows are to address memory problems introduced because of C++ (don’t quote me on that though). The point I’m trying to make is that PHP as a language is as much “enterprise ready” as any other language.

As programmers we invest a large amount of time in learning these things that often sit outside of the languages we choose. Well, it’s not wrong. The people who bring these things into the world (who are all a lot clever than me) generally do so for good reason. You have to be kidding me. However, it’s also bad to judge a language because of one piece of software. *Mixed : Mixed indicates that a parameter may accept multiple (but not necessarily all) types. Scaling applications to deal with millions of requests just isn’t a part of our normal day-to-day. With the recent release of PHP 8, “now” felt like the right time. PHP 6, the original PHP 6, has been discussed in detail in many PHP conferences. PHP 8.0 is due for release in November, but when this major new version appears Windows will not support it.

This isn’t a “my language is better than your language” rant, and I honest believe that every programming language has a purpose. 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 was taught to users as a done-deal, including detailed explanations about features and behavior (by php.net developers, not 'evil' book authors). Thanks for contributing an answer to Stack Overflow! It’s installed almost everywhere. I owe that to PHP. Tweaking here and there, but just couldn’t decide when to publish. Sometimes, you’ll see benchmarks between two different languages doing the same thing, like looping over a million records and doing some simple calculation. Smarty における {if} ステートメントは、PHP の if と同等の柔軟性を持っています。 さらに、テンプレートエンジンのための機能をいくつか追加しています。 全ての {if} は、対応する {/if} とペアである必要があります。
