PHP-FPM (PHP FastCGI Process Manager)
Created by: Andrey Pavlin. Written in C.

Pros:



#2 on the list of popular ways to run PHP applications.

It has good performance due north korea company email list to scaling of the worker pool.

Possibility of flexible pool configuration.

More debugging capabilities, including slow query log.

Cons:

More complex setup compared to Apache(mod_php).

It is necessary to configure interaction with the web server (Nginx).

Resource intensity: Each request is processed by a separate PHP process, which increases RAM consumption under high load. There is also overhead due to communication via FastCGI.

3. PHP-PM (PHP Process Manager)
Created by: Mark Schlichtenmaier. Written in PHP.

Pros:

Support for long-lived processes. As a result, the performance is better than php-fpm.

Asynchronous processing. PHP-PM uses ReactPHP to provide asynchronicity, which significantly speeds up the processing of requests.

Automatic reboot when code changes.

Cons:

It is necessary to monitor memory.

Requires a deeper understanding of how asynchronous PHP works.

Small community.

Less compatibility: Does not support all libraries and extensions that use synchronous mechanisms such as PDO or CURL, which operate in synchronous mode by default.

4. FrankenPHP
Created by Kevin Dunglas. Written in Go.

Pros:

Support for long-lived processes.

There is no need for a separate web server.

Supports asynchronous request processing.

Support for WebSockets and long-term connections.

Supported in laravel octane (a library that allows you to install Swoole, RoadRunner or FrankenPHP with one command, without having to write worker code) ( https://github.com/laravel/octane ).

Cons:

It is necessary to monitor memory.

Requires restart when code changes.

Requires a deeper understanding of how asynchronous PHP works.

Small community.

Without using laravel octane you need to write code for the worker.

Complex setup. Requires more complex setup and implementation into existing projects compared to traditional solutions such as php-fpm.
