Error installing Symphony 3.0.0 in PHP 7.3.7 about symphonycms

[nitriques]

@wdebusschere Thanks, I've found what is causing the problem. Sadly, I lost many hours trying to install rector, in the hope that it would fix the problem by itself, but it turns out, it does not fix that. So I resorted in fixing the code with a nasty regexp.

Find: , \$fields([^,)]+)
Replace with: , isset($fields$1) ? $fields$1 : null

Ahaha. rector does a super job to remove those isset() ternary with ??, but for now, all the code base uses this pattern.

Thanks @bauhouse for all those tests !
I think you are running with all errors (which is a good thing) but I something test (sadly) without the notices.

I assume you are getting the error when loading the installer (i.e. the install process has not yet begun?)

@nitriques, I am having the same error that @bauhouse is experiencing when running on Ubuntu 18.04, PHP 7.4.3, MySQL 5.7.26. This is on the installer page. Same exact error.

Thanks @bzerangue for reporting.

I also have this error with PHP 7.3.15 for the installer.
There are 2 errors in the log:
