title: Following PHP coding of Wisdom
body: <p>i read some wisdom like this : <blockquote>Programmers are encouraged to be careful when using by-reference variables since they can negatively affect the readability and maintainability of the code.</blockquote>
     <p>i make my own solution, such as give suffix such as <strong>_ref</strong> in every by-reference variables. so, if i have a variable named as <strong>$files_in_root</strong>, then i will add suffix and changes it name into <strong>$files_in_root_ref</strong>. As far my knowledge goes, this is a good solution.</p>
     <p>So, here come the question<ol>
     <li>Is there any best-practice on choosing suffix for by-reference variable in PHP coder world ? Or do you have any ?</li>
     <li>In general, how do we sustain readability and maintainability on PHP project with more then 3000 line of code ?</li>
     </ol></p></p>
  
  <p>I hope PHP coder world has unwritten aggrement for first question, cause it will help spot a pattern on any source code.</p>
