  PHP 5.4.16 (cli) (built: Nov 6 2016 00:29:02) Copyright (c) 1997-2013 The PHP Group Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies with the ionCube PHP Loader (enabled) + Intrusion Protection from ioncube24.com (unconfigured) v5.0.18, Copyright (c) 2002-2015, by ionCube Ltd.

Cause

Commands “php magento” or “./magento” are executed from a system PHP (PHP by OS vendor) which is not supported by Magento.

Note: The magento executable can be stored in /var/www/vhosts/example.com/httpdocs/bin/magento. So it might be needed to use the full way in the command.

Resolution

Run the command from within PHP version that domain uses:

Note: substitute ‘<command name>’ with an actual command required to execute.

# /opt/plesk/php/7.0/bin/php magento <command name>

or:

# /opt/plesk/php/7.0/bin/php ./magento <command name>

Alternatively, export path to a binary file of PHP 7.0 to the variable and run the command:

# export PATH=/opt/plesk/php/7.0/bin:$PATH
# ./magento <command name>
