PHP Code Sniffer Rules

<!-- PSR-2 but allow closing tags and with some Doc Comment stuff added -->
<ruleset name="AWonderPHP Standard 20180315">
  <![CDATA[
    These are the rules that I am trying to live by for all my php projects
    going forward.
    
    Nutshell - PSR-2 but allowing the closing ?> in pure PHP as I have a very
    stubborn fondness for the closing ?> tag and it mentally bothers me when it
    is not there. Rational? No, I have no problem with EOF being the closing
    tag for other programming language (e.g. Python) but to me PHP is different
    and for evidence of this - when you call #!/usr/bin/php in a shell script
    you *still* need the <?php opening tag.
    
    Additionally I turn off the PSR1 side effect check, it is a very valid rule
    but it comes naturally to me *except* when I code PHP shell scripts, the
    only place my php isn't pure php. And there, I want to be allowed to define
    functions within the shell script without needing them in an external file
    that has to be in the include path or included full path.
    
    This ruleset then adds a bunch of sniffs related to PHP documentation
    comment blocks.
    
    From a legal point of view, each file should have the author(s) and the
    license defined in a standard way that is easy to programmatically
    retrieve.
    
    From a code analysis point of view, each property and parameter should have
    a type defined and each method should have a return type defined so that
    code analysis tools can find potential bugs.
    
    TODO
    
    I need a sniff that looks for white space after the closing ?> tag.
    I need a sniff that ensure declare(strict_types = 1); is used.
