Subject: [PATCH] Swap argument order for implode

I noticed this squiggly red line while perusing the code.

The PHP doc says
`implode ( string $glue , array $pieces ) : string`
> implode() can, for historical reasons, accept its parameters in either order. For consistency with explode(), however, it may be less confusing to use the documented order of arguments.
