title: Php loop with different echo text
body: <p>I'm just started to learn php and have a lot of questions and all answers i found here, but i stucked on one problem and don't know which search words i need to use to find answer, so:
  I need to make some kind of loop with different echo text, but every new line should have $line+1, for example like this:</p>
  
  <pre><code>$line=1;
  Echo 'this line has number ='.$line;
  $line=$line+1;
  Echo 'this is second line'.$line;
  $line=$line+1;
  Echo ' third line'.$line;
  </code></pre>
  
  <p>I know that it simpliest way to do what i want, but php guru will make same thing in other easiest way. 
  Could you help m, please?</p>
