Inline adoc files when they are included exactly once. Also fix language tags because this inlining gives us better information on what language the code is written in.

== Why is this an issue?
|
|
|
|
Certain functions exist in PHP only as aliases of other functions. These aliases have been made available for backward compatibility, but should really be removed from code.
|
|
|
|
|
|
This rule looks for uses of the following aliases:
|
|
|
|
[frame=all]
|
|
[cols="^1,^1"]
