PHP基础----PHP常用功能----09include 与 require

index.php中：

<span style="font-size:24px;"><?php//include 与 require//主php文件/** * Created by PhpStorm. * User: zsgjs038 * Date: 2015/9/1 * Time: 11:27 *///错了之后提示错误//依赖 lib.php//require 'lib.php';//错了之后提示警告//包括 lib.php//include 'lib.php';//调用lib文件中的sayHello();方法//sayHello();//只依赖一次，不重复依赖//相当于把lib.php中的内容都复制到这里require_once  'lib.php';//调依赖文件中的方法sayHello();</span>

lib.php中：

<span style="font-size:24px;"><pre style="font-family: 宋体; font-size: 16pt; background-color: rgb(255, 255, 255);"><pre name="code" class="php"><?php//被依赖的php文件/** * Created by PhpStorm. * User: zsgjs038 * Date: 2015/9/1 * Time: 11:28 */function sayHello(){    echo 'hello php';}echo 'this is a lib file';</span>
