After doing some research on the site this error occurs because of the php.ini file most likely including a reference to load the extension when it was already compiled into the PHP.

That said, I'm using Docker and Docker-Compose. I found a way to keep the default php.ini file and any changes would be overwritten through my custom.php.ini file.

This works because of this... (This is just a small snippet from my docker-compose.yml file)

web:
        build: ./
        depends_on:
            - dblive
            - dbdev
        volumes:
            - ./web:/var/www
            - ./config/custom.php.ini:/etc/php5/apache2/conf.d/custom.php.ini

notice that I have my own custom.php.ini file and it maps into the directory where PHP looks for extra php.ini files. This works perfectly.

Currently in this custom.php.ini file I have this.

asp_tags = Off
display_errors = On
display_startup_errors = On

I'm getting an error currently like this...

PHP Warning:  Module 'curl' already loaded in Unknown on line 0

Warning: Module 'curl' already loaded in Unknown on line 0

How can I edit this external php.ini file to disable loading the extension?

Possible Alternative Solution

Because of the way I run this I also have a run script that Docker runs when it starts to modify the initial php.ini file.

It looks like this...

#!/bin/bash
set -e

#Edits to the default php.ini file go here
PHP_ERROR_REPORTING=${PHP_ERROR_REPORTING:-"E_ALL & ~E_DEPRECATED & ~E_NOTICE"}

sed -ri 's/^display_errors\s*=\s*Off/display_errors = On/g' /etc/php5/apache2/php.ini
sed -ri 's/^display_errors\s*=\s*Off/display_errors = On/g' /etc/php5/cli/php.ini
sed -ri "s/^error_reporting\s*=.*$//g" /etc/php5/apache2/php.ini
sed -ri "s/^error_reporting\s*=.*$//g" /etc/php5/cli/php.ini

echo "error_reporting = $PHP_ERROR_REPORTING" >> /etc/php5/apache2/php.ini
echo "error_reporting = $PHP_ERROR_REPORTING" >> /etc/php5/cli/php.ini

source /etc/apache2/envvars && exec /usr/sbin/apache2 -DFOREGROUND

This allows overwriting of some default values but I'm not sure what to change here to disable cURL (If this is even the best place to do it?)

This error occurs when I'm using composer, I checked the php.ini files but don't seem to see cURL loaded there?

Result of php.info here

Disable cURL extension from loading since we compile it with PHP

sed -i "s/extension=curl.so/;extension=curl.so/g" /etc/php5/apache2/conf.d/20-curl.ini

I ran this command to disable it from the 20-curl.ini file that I found out was loading the extension. I did this in my run script from the Dockerfile.
