_php techniques for define usages in PHP

The example in this article tells about define usage in PHP. Share to everyone for your reference. Specifically as follows:

<?php
/
 * Define * */////////////////////////////////////
 3rd
 "Pai", 3.14);
 Define ("name", "Lilei", true);
 function Testfor ($x) {for
  ($a = $x; $a <=12; $a + +) {
    echo "is now $a point:";
    if ($a <9) {
      echo "knock Code";
      echo name;
    } else {
      echo "sleeps";
      echo pai;
    }
    echo "<br/>";
  }
 Testfor (a);
>

The results of the operation are as follows:

Now it's 10: Sleep 3.14.
Now it's 11: Sleep 3.14.
Now it's 12: Sleep 3.14.

I hope this article will help you with your PHP program design.
