但是我的机器上是有的啊？

我也遇到了，但是不清楚是什么原因？可能确实和 PHP 有关！

Apart from the framing of this post more as an apology than as a show of strength of keeping things simple and sturdy, interesting nuggets: Epub ebooks are xhtml and static so rapidly served without the need for a fancy framework or even a database. Flat texts are small, and their current collection fits in RAM entirely. PHP is used without frills. All in all a strong call to keep things simple, and to embrace my current use of php for local tools too: it's very fast.

Also makes me wonder: #openvraag what can one do with Epub books outside an ebook reader, in terms of excerpting e.g. and ripping things out for re-use elsewhere. I've got loads of them on my laptop

```php

PHP est un langage de script utilisé le plus souvent côté serveur : dans cette architecture, le serveur interprète le code PHP des pages web demandées et génère du code (HTML, XHTML, CSS par exemple) et des données (JPEG, GIF, PNG par exemple) pouvant être interprétés et rendus par un navigateur web. PHP peut également générer d'autres formats comme le WML, le SVG et le PDF.

Same solution but in PHP

php function hints() { header("link: </wp-content/themes/phpied2/style.css>; rel=preload, </wp-includes/css/dist/block-library/style.min.css?ver=5.4.1>; rel=preload"); } add_action('send_headers', 'hints');

array_replace() replaces the values of array with values having the same keys in each of the following arrays.

首先，跨域请求分为两种，一种是简单请求，即get请求和post请求（不带多余的请求头），这种情况下，浏览器会直接请求，在有允许跨域的头的情况下，予以显示。（这里并不是说没有跨域头服务器就不返回数据了，数据是照常返回的，但是浏览器拦截了返回数据。） 另一种呢是复杂请求，即非get或post请求，或者是有了自定义头的请求。这种情况下，浏览器会首先发送一个options请求（预请求），来确是否允许跨域。在服务器返回的跨域条件都允许之后，浏览器才会发送正式请求。

php,请求跨域接口；执行了两次请求；OPTIONS（预处理）；get(真正请求)；

按理来说，OPTIONS（预处理） 只是判断 header('Access-Control-Allow-Headers:x-requested-with,content-type');是否通过；通过了，才执行get； 现在出现的问题是，OPTIONS请求也执行了一次程序；然后get也执行了一次程序；

解决办法： if (strtolower($_SERVER['REQUEST_METHOD']) == 'options') { exit; }

Meaning you need to append "-apache" to the image name to have Apache with PHP.

When to use different programming languages (advice from an Amazon employee):

• Java - enterprise applications
• C# - Microsoft's spin on Java (useful in the Microsoft's ecosystem)
• Ruby - when speed is more important then legibility or debugging
• Python - same as Ruby but also for ML/AI (don't forget to use type hinting to make life a little saner)
• Go/Rust - fresh web service where latency and performance were more important than community/library support
• Haskell/Erlang - for very elegant/mathematical functional approach without a lot of business logic
• Clojure - in situation when you love Lisp (?)
• Kotlin/Scala - languages compiling to JVM bytecode (preferable over Clojure). Kotlin works with Java and has great IntelliJ support
• C - classes of applications (operating systems, language design, low-level programming and hardware)
• C++ - robotics, video games and high frequency trading where the performance gains from no garbage collection make it preferable to Java
• PHP/Hack - testing server changes without rebuilding. PHP is banned at Amazon due to security reasons, but its successor, Hack, runs a lot of Facebook and Slack's backends
