title: PHP "backspace" character during output possible?
body: <p>I have a feeling the answer is "it's not possible," but thought I'd ask to satisfy my curiosity.</p>
  
  <p>I have some code that's echoed where the \n is unavoidable:</p>
  
  <pre><code>echo "Hello \n";
  echo "World!";
  </code></pre>
  
  <p>I'd like the line to simply read (in the code output):</p>
  
  <blockquote>
    <p>Hello World!</p>
  </blockquote>
  
  <p>... thus removing the \n.</p>
  
  <p>So I was wondering if it's possible to execute a "backspace" character during PHP's output?</p>
  
  <p>Something simple like <code>str_replace( "\n", 'backspace-character', $str );</code></p>
