title: PHP, why sometimes "\n or \r" works but sometimes doesnt?
body: <p>Well, I am abit confuse using these \r,\n,\t etc things. Because I read online (php.net), it seems like works, but i try it, here is my simple code:</p>
  
  <pre><code>&lt;?php
      $str   = "My name is jingle \n\r";
      $str2  = "I am a boy";
  
      echo $str . $str2;
  ?&gt;
  </code></pre>
  
  <p>But the outcome is "My name is jingle I am a boy"</p>
  
  <p>Either I put the \r\n in the var or in the same line as echo, the outcome is the same. Anyone knows why?</p>
