The <info>%command.name%</info> command executes a migration to a specified version or the latest available version: |
|
35
|
|
|
|
|
36
|
|
|
<info>%command.full_name%</info> |
|
37
|
|
|
|
|

You can optionally manually specify the version you wish to migrate to: |
|
39
|
|
|
|
|
40
|
|
|
<info>%command.full_name% YYYYMMDDHHMMSS</info> |
|
41
|
|
|
|
|
42
|
|
|
Or you can also execute the migration without a warning message which you need to interact with: |
|
43
|
|
|
|
|
44
|
|
|
<info>%command.full_name% --no-interaction</info> |

This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent.
Consider making the comparison explicit by using
empty(..)or! empty(...)instead.
