title: PHP Remove Text Between [ and ] Parentheses
body: <p>I need to remove text included between [ and ] parentheses (and parentheses, too).</p>
  
  <p>For example:</p>
  
  <p>Hello, [how are you]</p>
  
  <p>Must become:</p>
  
  <p>Hello,</p>
  
  <p>And, a string like:</p>
  
  <p>hello, [how][are] you</p>
  
  <p>must become: </p>
  
  <p>hello, you</p>
  
  <p>There is a regula expression to do that?</p>
