PSR-2 [1] is a highly regarded style guide in the PHP community
according to Stack Overflow [2].
The indentation was out of place in the source code. I've seen a
combination of 1 space tabs, 3 space tabs, 4 space tabs and 5 space
tabs. Some closing braces on the same line and a lot of the code
(especially moe code) had reached the point of losing readability.
Converted with php-cs-fixer and some hand adjustment.
