Answer 1

Please change the PHP version of your terminal using

sudo update-alternatives --set php /usr/bin/php7.2

Change PHP version according to your Magento version. E.g. for Up to Magento 2.3.2 PHP 7.2 is highest version

Answer 2

Most of the time downgrading PHP is not feasible. So until we get fix from Magento here is a work around

As of PHP 7.3, a warning will be thrown when continue is used within a switch without a numeric argument. Ref: php/php-src@04e3523

So changing core files solve the issue.

1. Change continue to continue 2 in vendor/zendframework/zend-stdlib/src/ArrayObject.php @ line 426.
2. Change continue to continue 2 in vendor/magento/zendframework1/library/Zend/Pdf/FileParser/Font/OpenType.php @ line 901.
3. Change continue to continue 2 in vendor/magento/zendframework1/library/Zend/Pdf/FileParser/Font/OpenType.php @ line 920.
4. Change continue to continue 2 in vendor/magento/zendframework1/library/Zend/Pdf/FileParser/Font/OpenType.php @ line 932.

Now try doing bin/magento setup:upgrade. It will work ..!!

Answer 3

This issue happens due to PHP changes and now need to use "continue 2" withing "switch" case.

You need to changes the vendor\zendframework\zend-stdlib\src\ArrayObject.php at line #426

continue

TO

continue 2
