Not working on install with official doc

[fabienlege]

I've tried to install this tool but I've an error when I follow install instruction.

On database creation (bin/console orm:schema-tool:create) i've got this error :

[ErrorException]                                                                         
  "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"?  

here my php -v :

This project does not seem to be compatible with PHP 7.3 (yet). Take a look at the "Continue Targeting Switch issues Warning" section in https://www.php.net/manual/en/migration73.incompatible.php.
