cli console handler "wrong" php version

[stfast]

We are running Phalcon 3.4.5 on php-fpm with PHP 7.3 which is one of multiple concurrent versions of PHPs on the server.

Is it possible to set custom PHP version which is exectued by $console->handle() in cli.php

Default PHP on $PATH is PHP 8.0

$ /usr/bin/php -v
PHP 8.0.25 (cli) (built: Oct 25 2022 09:42:31) ( NTS gcc x86_64 )
Copyright (c) The PHP Group
Zend Engine v4.0.25, Copyright (c) Zend Technologies
with Zend OPcache v8.0.25, Copyright (c), by Zend Technologies
with Xdebug v3.1.6, Copyright (c) 2002-2022, by Derick Rethans

but one with Phalcon module is, PHP 7.3 on path

$ /usr/local/php-7.3/bin/php -v
PHP 7.3.33 (cli) (built: Jan 10 2022 16:31:24) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.3.33, Copyright (c) 1998-2018 Zend Technologies
with Zend OPcache v7.3.33, Copyright (c) 1999-2018, by Zend Technologies

When we process our Cli tasks with $console->handle() it picks wrong version of PHP 8.0 instead of 7.3.

use Phalcon\Cli\Console;
use Phalcon\Cli\Dispatcher;
use Phalcon\Di\FactoryDefault\Cli as FactoryDefault;

$console = new Console();
$console->setDI($di);
$console->handle($arguments);

It is executing

php cli.php tenant vasco syncorder d1bc2d8f-39ea-4072-a967-418f821474f0

but we wont, that $console->handle executes

/usr/local/php-7.3/bin/php cli.php tenant vasco syncorder d1bc2d8f-39ea-4072-a967-418f821474f0

Not working:

$ php cli.php

Working:

$ /usr/local/php-7.3/bin/php cli.php

PHP Warning: Use of undefined constant TENANT_PATH - assumed 'TENANT_PATH' (this will throw an Error in a future version of PHP) in ../application/app/config/config.php on line 24

You can change the default php version as below:
sudo update-alternatives --config php

About warning "PHP Warning: Use of undefined constant TENANT_PATH", you can comment out or delete where to include config.php file in cli.php

The issue isn't that $console-handle() is picking the wrong version. It's a PHP script - by the time it started running, the PHP version is determined. cli.php isn't the program - php is. In your working version you specified the php executable for 7.3 - you're just going to have to continue doing that or alias php to that version - though that would be a system-wide change.
