require/import vs require/include in PHP Coding Standards Documentation. - Fix for #143 (#144)

* Update php.md
  * Changed order to alphabetical order: include, require to be consistent with lines 81-83 (Writing include/require statements) and made clear that autoloading only applies to classes.

 Text that goes into HTML or XML attributes should be escaped so that single or double quotes do not end the attribute value and invalidate the HTML, causing a security issue. See [Data Validation](https://developer.wordpress.org/plugins/security/data-validation/) in the Plugin Handbook for further details.

-Because `include[_once]` and `require[_once]` are language constructs, they do not need parentheses around the path, so those shouldn't be used. There should only be one space between the path and the include/require keywords.

 It is _strongly recommended_ to use `require[_once]` for unconditional includes. When using `include[_once]`, PHP will throw a warning when the file is not found but will continue execution, which will almost certainly lead to other errors/warnings/notices being thrown if your application depends on the file loaded, potentially leading to security leaks. For that reason, `require[_once]` is generally the better choice as it will throw a `Fatal Error` if the file cannot be found.

-Note that, unless you have implemented [autoloading](https://www.php.net/manual/en/language.oop5.autoload.php), the `use` statement won't automatically load whatever is being imported. You'll either need to set up autoloading or load the file containing the class/function/constant using a `require/import` statement, for the imported constructs to be loaded when used.
