PHP 有没有花式定义函数的办法？

[moult]

$funcList = array(
    'foo' => function(){},
    'bar' => function(){}
);
foreach($funcList as $funcName=>$closure){
    // 循环将 funcList 里面的函数抽取到外面!
    // function $funcName{ $closure(); }
}

```
<?php

class a {
protected $x = "x";

public function xy() {
$funcList = array(
'foo' => function() { echo "a"; },
'bar' => function() { echo "b"; }
);

foreach ($funcList as $funcName => $closure) {
$closure();
}
}
}

$a = new a();
$a->xy();
```


或者


```
<?php

class b {}

$obj = new b();
$obj->yz = function () {
return 'b';
};
echo($obj->yz->__invoke());
```

不过。。。。有啥意义么
