Help installing php extension PCNTL

CharlieC

Hi, does anybody know how to install this php extension called pcntl on ubuntu/debian?

I need it to use a github repo which allows me to create async functions in php.

Read the docs?

https://www.php.net/manual/en/pcntl.installation.php

CharlieC

I've tried to do so but failed, I can pay if someone help installing it

Maybe I will compile bullseye packages later this week. Which PHP version you are looking for?

CharlieC

Any above 7.0 is fine, thank you

Maybe have a try as this - https://stackoverflow.com/questions/40408152/how-to-enable-pcntl-on-ubuntu-server-16-04

There is a high chance that pcntl is installed but its functions are in disabled_functions in php.ini.

Can you run this command real quick?

php -i | grep pcntl

php -i | grep pcntl

root@vm:/var/www/html/async# php -i | grep pcntl
pcntl
pcntl support => enabled

I've removed "disabled_functions" line from php.ini file and restarted both php and nginx, still the script tells me "The pcntl functions cannot be found. Is the pcntl extension installed?"

Hi, which script you used to test if pcntl functions? Maybe I will try to test on my local debian box.

Oh...yes, I need your help, because I do not know about php programing.

I put files from src directory to apache htdocs path, browsing helpers.php, it just show blank. I also try to copy 'Getting Started' example to test, but it show error - Fatal error: Uncaught Error: Call to undefined function async() in...

I think i have to set it up to see what's causing the issue.

There is a high chance that your php.ini of cli and php-fpm are different.

You are modifying CLI version but expecting changes in php-fpm using nginx.

Could you confirm by creating a phpinfo.php file with a simple phpinfo function in www webroot and hitting it from web?

It would display if pcntl is really loaded or not

CharlieC

Hmm seeing this I think its not loaded somehow

But I have edited both cli and fpm ini files.

I can pay if anyone is able to install it for me

Which php ini did you change?

Also you can pm me any desk details and we both can figure it out ☺️

noaman is right.

In my local debian php7.4 box, php cli is okay, but apache2 not, script said:
Fatal error: Uncaught RuntimeException: The pcntl functions cannot be found. Is the pcntl extension installed? in /var/www/magen2/vendor/superrb/async/src/Superrb/Async/Handler.php:75

But when I did as rainysia said on https://stackoverflow.com/questions/14096130/enable-pcntl-in-ubuntu-php-test-fails

apache2 can show 'pcntl support' now, script show another error as php cli:
Fatal error: Uncaught TypeError: Argument 1 passed to Superrb\Async\Socket::__construct() must be an instance of Socket, resource given, called in /var/www/magen2/vendor/superrb/async/src/Superrb/Async/Channel.php on line 52

So, maybe have to create pcntl.so using phpize(php7.4-dev), then load it for apache2.
