Stop PhpStorm from aligning associative arrays

Question

How can I tell PhpStorm (using version 8.0.3) to keep the following array as is when clicking Cmd+Alt+L to reformat my code:

$array = [
    'short' => 1, // I want this...
    'veryVeryVeryIncrediblyLong' => 123456789,
];

Instead of doing this:

$array = [
    'short'                      => 1, // Not this...
    'veryVeryVeryIncrediblyLong' => 123456789,
];

Answer 1

Since PhpStorm 2017.x version the appropriate option is located at:

• Settings (Preferences on Mac) | Editor | Code Style
• PHP | Wrapping and Braces
• Array initializer | Align key-value pairs
