Enhancement: Include `*.inc` files (with exceptions)

Closes GH-662.

Fix: Heredoc syntax

Closes GH-564.

Multiple micro-optimizations

* Replace `ob_get_contents();ob_clean()` with `ob_get_clean()`

`ob_get_clean()` is equivalent to `ob_get_contents()` followed by `ob_clean()`.

Multiple micro-optimizations

* Replace `ob_get_contents();ob_clean()` with `ob_get_clean()`

`ob_get_clean()` is equivalent to `ob_get_contents()` followed by `ob_clean()`.

* Replace `intval()` calls with `(int)` type cast

This is a micro-optimization because `intval()` is a function call, and the type cast is about 6 times fast.

* Replace `preg_replace` call that could be done with an `rtrim()` call

In `./error.php`, there is a `preg_replace('!/+$!', '', $URI);` call that essentially is equivalent to `rtrim()`, that both calls removing trailing slash characters in `$URI`.
The `rtim()` call is more legible and faster.

* Combine consecutive `str_replace` calls to a single `str_replace` call

* Use short ternary operator where possible

Improves code readability.

* Cascade various `else` statements where possible

Cleans up the code by removing unnecessary `else` blocks and moving the code to the parent context if the previous `if` block exits the function by either terminating the script, or with a `return` statement.

* Combine multiple `isset()` calls to a single `isset()`

`isset()` accepts multiple parameters and returns `true` only if all of the parameters are `isset`. It makes sense to combine multiple individual `isset` calls to a single call for better readability.

* Replace `for` loop with a `foreach` loop

* Remove unnecessary character escapes in regular expressions

Regular expression special characters are context-sensitive. For example, special characters such as `.` are not considered special within square braces (`[]`).
This removes several of such instances that certain characters are escaped, but it is not strictly necessary within the context. This improves the readability of the expression.

* Remove unnecessary break statement

* Remove unnecessary PHP close tags

* Remove redundant JSON_ERROR_NONE check

Remove unnecessary `json_last_error() == JSON_ERROR_NONE` where the decoded object is inspected already.

Closes GH-603.
