问一个语法的问题

<br /><br />route('/', function(){<br />    echo 'hello world!';<br />});<br />//这是什么意思呢.没见过这种语法格式<br />

------解决方案--------------------
闭包，php5.3开始支持

route('/', function(){<br />    echo 'hello world!';<br />});

中 route 是一个自定义函数，他需要传入两个参数，而第二个参数是一个回调函数

对于 php < 5.3，可写作

route('/', create_function('', "echo 'hello world!';"));

他们都可视为

function func(){<br />    echo 'hello world!';<br />}<br />route('/', 'func');

的简写形式
