How to enable pcntl in php (when using a framework like Symfony2)

c:\xampp\htdocs\login>php app/console server:start

An extension is required to execute this command pcntl.

This is the error I get when I try to start a web server in my environment symfony2.

I found a fix using the command:

$ php app/console server:run

But does anyone know why it server:startdoesn't work on my desktop? Thanks in advance.

My goal:

Web server launch

Running a Symfony application using the PHP embedded web server is as easy as running a command server:start:

$ php app/console server:start

php-extension-library github contains several pcntl.so files that you can easily download for your version of PHP and add .ini to your extensions.

For example, for php version 7.3.9:

  1. Download pcntl.so from the repository here or right here .
  2. Move the file pcntl.soto the extension (for example: /Applications/MAMP/bin/php/php7.3.9/lib/php/extensions/no-debug-non-zts-xxxxxxxx)
  3. Add extension=pcntl.soto your.ini
