… "PHP" class (#1457) > [!WARNING] > This is breaking change! Review the description below to assess the impact on your app. Consolidates the `BasePHP`, `NodePHP`, and `WebPHP` classes into a single `PHP` class. This refactor reduces redundancy and clarifies the PHP handling process across different environments. ## Examples ### NodePHP **Before** ```ts import { NodePHP } from '@php-wasm/node'; const php = await NodePHP.load('8.0'); ``` **After** ```ts import { loadNodeRuntime } from '@php-wasm/node'; import { PHP } from '@php-wasm/universal'; const php = new PHP(await loadNodeRuntime('8.0')); ``` ### WebPHP **Before** ```ts import { WebPHP } from '@php-wasm/web'; const php = await WebPHP.loadRuntime('8.0'); ``` **After** ```ts import { loadWebRuntime } from '@php-wasm/web'; import { PHP } from '@php-wasm/universal'; const php = new PHP(await loadWebRuntime('8.0')); ``` ### Mounting **Before** ```ts php.useHostFilesystem(); // or php.mount( '/home/users/adam/my-dir', '/my-dir-in-vfs'); ``` **After** ```ts import { NodeFSMount, useHostFilesystem } from '@php-wasm/node'; useHostFilesystem( php ); php.mount( new NodeFSMount( '/home/users/adam/my-dir' ), '/my-dir-in-vfs' ); ``` Closes #1399 ## Motivation First, the public API surface of all the PHP classes and interfaces is [overly complex](#514). This PR is a step towards simplifying it. Second, in the [Boot Protocol](#1398), PR the `bootWordPress()` function requires separate `createPHP` and `createPHPRuntime` callbacks just because Playground uses different classes in node.js and in the browser. With this PR, `createPHP` callback will no longer be needed anymore as `bootWordPress()` will just always create a `new PHP()` instance. ## Public API Changes - Removes `BasePHP`, `NodePHP`, and `WebPHP` classes in favor of a single PHP class exported from `@php-wasm/universal` - `php.useHostFilesystem()` was removed in favor of a decoupled function `useHostFilesystem( php )` available in `@php-wasm/node`. - `PHP.mount()` signature changed from `mount( hostPath: string, vfsPath: string )` to `mount( mountable: Mountable, vfsPath: string )` - Moves WebPHPEndpoint from `@php-wasm/web` to `@php-wasm/universal` and renames it to `PHPWorker`. That class isn't specific to the web and could be easily used by Node workers. - Removes the `IsomorphicLocalPHP` interface. The PHP class is now the source of truth for all derived worker, client, etc. implementations. - Removes the `createPhpInstance()` option from `bootWordPress( options )` in favor of always using the PHP class. - Updates to Documentation: Adjusted examples and references in the documentation to reflect the new `PHP` class. - Refactoring of Test Suites: Updated tests to work with the new class structure. ## Testing instructions Confirm all the CI checks pass – this PR includes an extensive refactor of all the tests.

The existence of separate
NodePHPandWebPHPclasses adds complexity without creating much value. The underlying runtime is the deciding factor when it comes to supported features anyway. Let's pull all their non-static methods intoBasePHP, rename it toPHP, and use that. The static runtime-loading methods could be just regular functions. It should save us a lot of abstraction and typing conundrums.Related to #514
