php中define用法实例,phpdefine用法实例

本文实例讲述了php中define用法。分享给大家供大家参考。具体如下:

<&#63;php
/*
 * define
 * */
 /*第3个参数:
 * false -- 对大小写敏感(默认)
 * true -- 对大小写不敏感
 * */
 define("pai",3.14);
 define ("name","LiLei",true);
 function testfor($x) {
  for($a=$x;$a<=12;$a++) {
    echo "现在是$a 点:";
    if($a<9) {
      echo "敲代码";
      echo name;
    } else {
      echo "睡觉";
      echo pai;
    }
    echo "<br />";
  }
 }
 testfor(10);
&#63;>

运行结果如下:

现在是10 点:睡觉3.14
现在是11 点:睡觉3.14
现在是12 点:睡觉3.14

希望本文所述对大家的php程序设计有所帮助。
