Christian WeiskePHP: file_get_contents with basic auth and redirects (20.9.2020, 17:11 UTC)

I used PHP's file_get_contents() to fetch the content of an URL:

$content = file_get_contents('https://username:password@example.org/path');

This worked fine until that URL redirected to a different path on the same domain. An error was thrown then:

PHP Warning: file_get_contents(http://...@example.org): failed to open stream: HTTP request failed! HTTP/1.1 401 Unauthorized

The solution is to use a stream context and configure the HTTP basic auth parameters into it. Those parameters are used for redirects, too.

$user = 'user';
$pass = 'pass';
$opts = [
    'http' => [
        'method' => 'GET',
        'header' => 'Authorization: Basic ' . base64_encode($user . ':' . $pass)
    ]
];
file_get_contents($baUrl, false, stream_context_create($opts));

Christian WeiskeLaravel: Finding the route name (20.9.2020, 08:38 UTC)

Recently at work I had to analyze a problem in a Laravel application that I was not familiar with. The problem: When calling a specific URL, it wrongly redirected to another URL.

The route that I expected to be called was not, and routes/web.php was huge; too large to find the matching route quickly.

The solution was to adjust public/index.php and add the following line before the response was sent back to the browser:

$response->header('X-Route', Route::currentRouteName());
$response->send();

Now I could look at the redirect's HTTP headers to find the route that had been used:

$ curl -I http://app.example.org/en/explanatory-videos/test-510/
HTTP/1.1 302 Found
Date: Wed, 16 Sep 2020 11:45:26 GMT
Server: nginx/1.10.3 (Ubuntu)

Derick Rethans 0:15

Hi, I'm Derick, and this is PHP internals news, a weekly podcast dedicated to demystifying the development of the PHP language. This is Episode 68. Today I'm talking with Levi Morrison, and Sammy Powers, about something called the observer API, which is something that is new in PHP eight zero. Now, we've already passed feature freeze, of course, but this snuck in at the last possible moment. What this is observer API going to solve?

Levi Morrison 0:44

the observer API is primarily aimed at recording function calls in some way so it can also handle include, and require, and eval, and potentially in the future other things, but this is important because it allows you to write tools that automatically observe, hence the name, when a function begins or ends, or both.

Derick Rethans 1:12

What would you use that for?

Levi Morrison 1:13

So as an example, Xdebug can use this to know when functions are entered or or left, and other tools such as application performance monitoring, or APM tools like data dog, New Relic, tideways, instana so on, they can use these hooks too.

Derick Rethans 1:38

From what I understand that is the point you're coming in from, because we haven't actually done a proper introduction, which I forgot about. I've been out of this for doing this for a while. So both you and Sammy you work for data dog and work on their APM tool, which made you start doing this, I suppose.

Sammy Kaye Powers 1:54

Yeah, absolutely. One of the pain points of tying into the engine to to monitor things is that the hooks are insufficient in a number of different ways. The primary way that you would do function call interception is with a little hook called zend_execute_ex and this will hook all userland function calls. The problem is, it has an inherent stack bomb in it where if, depending on your stack size settings you, you're going to blow up your stack. At some point if you have a very very deeply deep call stack in PHP, PHP, technically has a virtually unlimited call stack. But when you use zend_execute_ex, it actually does limit your stack size to whatever your settings are your ulimit set stack size. One of the issues that this solves is that stack overflow issue that you can run into when intercepting userland calls but the other thing that it solves is the potential JIT issues that are coming with PHP eight, where the optimizations that it does could potentially optimize out a call to zend_execute_ex where a profiling or APM tracing kind of extension would not be able to enter set that call, because of the JIT. The Observer API enables to solve multiple issues with this. Not only that, there's more. there's more features to this thing, because zend_execute_ex by default will intercept all userland function calls, and you have no choice but to intercept every single call, whereas, this API is designed to also allow you to choose which function calls specifically you want to intercept, so there is on the very first call of a function call. And it'll basically send in the zend function. This is a little bit of a point we've been kind of going back and forth on what we actually send in on the initialis

PHP: Hypertext PreprocessorPHP 8.0.0 Beta 4 available for testing (17.9.2020, 00:00 UTC)
The PHP team is pleased to announce the seventh testing release of PHP 8.0.0, Beta 4. This point in the release cycle would normally be RC1, however we're still finalizing development of the JIT and squaring away named arguments, so we've opted for an extra beta release with plans to start the RC cycle in two weeks. At this time, we're not planning to adjust the GA date, however this may change during the course of the RC cycle. The updated release schedule can, as always, be found on the PHP Wiki. For source downloads of PHP 8.0.0 Beta 4 please visit the download page.Please carefully test this version and report any issues found in the bug reporting system.Please DO NOT use this version in production, it is an early test version. For more information on the new features and other changes, you can read the NEWS file, or the UPGRADING file for a complete list of upgrading notes. These files can also be found in the release archive. The next release will be the Release Candidate 1, planned for Oct 1 2020.The signatures for the release can be found in the manifest or on the QA site.Thank you for helping us make PHP better.

Cees-Jan KiewietBuilding the next generation react/http PSR-15 adapter (11.9.2020, 00:00 UTC)

Two and a half years ago I wrote how to use RecoilPHP to create a PSR-15 middleware adapter for react/http using coroutines, monkey patching, and autoloader hijacking. Today there is a followup on that without any coroutines, monkey patching, and autoloader hijacking. But using ext-parallel instead, react-parallel/psr-15-adapter was created.

Evert PotKetting v6: Using Hypermedia APIs with React (9.9.2020, 20:30 UTC)

We just released Ketting 6. This is the accumulation of about a year of learning on how to better integrate REST APIs with frontend frameworks, in particular React.

It’s packed with new features such as local state management, new caching strategies, (client-side) middleware support and change events. It’s also the first release that has some larger BC breaks to make this all work.

Releasing Ketting 6 is a big personal milestone for me, and I’m really excited to unleash it to the world and see what people do with. A big thank you to all the people that beta tested this in the last several months!

What’s Ketting?

In short: Ketting is a generic REST client for Javascript. You can use it for pushing JSON objects via HTTP, but the richer your API is in terms of best practices and standard formats, the more it can automatically do for you.

It has support for Hypermedia formats such as HAL, Siren, Collection+JSON, JSON:API and can even understand and follow links from HTML.

It’s often said that REST (and Hypermedia APIs) is lacking a good generic client. GraphQL has a lot of advantages, but a major one is tooling. Ketting aims to close that gap.

More information can be found on Github.

React support in Ketting 6

Ketting now has a separate react-ketting package that provides React bindings to Ketting. These bindings should look very familiar if you’ve used Apollo Client in the past.

Lets dive into an example:

Lets assume you have a REST api that has an ‘article’ endpoint. This returns something like:

{
  "title": "Hello world",
  "body": "..."
}

This article is retrieved with GET, and updated with PUT, this is how you would display it:

import { useResource } from 'react-ketting';


export function Article() {

  const { loading, error, data } = useResource('https://api.example/article/5');

  if (loading) {
    return <div>Loading...</div>;
  }

  if (error) {
    return <div class="error">{error.message}</div>;
  }

  return <article>
    <h1>{data.title}<
