How to find the files that are the slowest to analyze with PHPStan?

For us, PHPStan became a bit slower with every release. We have a very large codebase with 10.000+ classes. There seem to be a few known issues related to big arrays.

See: phpstan/phpstan#8353 phpstan/phpstan#8146

To understand which files are problematic we run the following command:

<?php

declare(strict_types=1);

namespace App\Metadata;

use ApiPlatform\Core\Metadata\Property\Factory\PropertyMetadataFactoryInterface;
use ApiPlatform\Core\Metadata\Property\PropertyMetadata;

final class PropertyMetadataFactory implements PropertyMetadataFactoryInterface

const isWalkable = value => value !== null && typeof value !== 'undefined';
const getChild = (parent, child) => (isWalkable(parent) ? parent[child] : undefined);
const getIn = (descendants, origin) => descendants.split('.').reduce(getChild, origin);

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

• elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

1. Raw Attribute Strings

   <div my-directive="some string" another-param="another string"></div>

<?php

class Foo
{
    protected $foo;
    protected $bar;
    protected $baz;

    $timer = microtime(true);
    $hSock = fopen($sURL, 'rb');
    $length = 10240;
    if ($hSock) {
      while(!feof($hSock)) {
        $vData = fread($hSock, $length);

Backstory: I decided to crowdsource static site generator recommendations, so the following are actual real world suggested-to-me results. I then took those and sorted them by language/server and, just for a decent relative metric, their Github Watcher count. If you want a heap of other projects (including other languages like Haskell and Python) Nanoc has the mother of all site generator lists. If you recommend another one, by all means add a comment.
