Code-Hero comes with asdf, a utility that allows you to easily select the PHP version you need.

By default, the latest PHP version is installed. You can check the installed version by running:

php -v

Change the default PHP version

If you want to use a different PHP version, follow these steps:

1. Update all plugins:

   asdf plugin update --all
   

2. List all available PHP versions:

   asdf list all php
   

3. Install the desired version:

   asdf install php <VERSION>
   

After installing the desired version, decide whether you want to use it globally or locally:

1. To use it globally (across all directories), run:

   asdf global php <VERSION>
   

2. To use it locally (for the current directory only), run:

   asdf local php <VERSION>
   

   This command creates a .tool-versions file in the current directory containing the chosen version information.

To verify which version is active, run:

php -v

How to add PHP extensions

Adding PHP extensions is straightforward. For example, to install the AMQP extension (which is useful for connecting to a RabbitMQ server), follow these steps:

1. Install the extension using PECL:

   pecl install amqp
   

2. Add the extension to your PHP configuration by appending it to your php.ini file:

   echo "extension=amqp.so" >> $(asdf where php)/conf.d/php.ini
   

3. Check that the extension is enabled:

   php -i | grep amqp
   

To list all currently installed extensions, run:

php -m
