如何使连锁目标在PHP5类? 例子:
$myclass->foo->bar->baz();
$this->foo->bar->baz();
Not: $myclass->foo()->bar()->baz();
也可以看看:

只要你的$ MyClass的有一个成员/属性,是一个实例本身它的作用类似。
class foo {
public $bar;
}
class bar {
public function hello() {
return "hello world";
}
}
$myclass = new foo();
$myclass->bar = new bar();
print $myclass->bar->hello();
其实这个问题是模糊的....对我来说这@地理的答案是正确的。
你(@Anti)说,可能是成分
这是我在这个例子:
<?php
class Greeting {
private $what;
private $who;
public function say($what) {
$this->what = $what;
return $this;
}
public function to($who) {
$this->who = $who;
return $this;
}
public function __toString() {
return sprintf("%s %s\n", $this->what, $this->who);
}
}
$greeting = new Greeting();
echo $greeting->say('hola')->to('gabriel'); // will print: hola gabriel
?>
为了链函数调用那样,通常你返回从功能自(或本)。
