PHP代码格式化程序/美化程序和一般的PHP美化[关闭]

你知道有什么好的工具可以很好地格式化凌乱的 php 代码吗？最好是 Aptana/Eclipse 的脚本，但独立工具也可以。

这是我非常基本和粗略的脚本：

#!/usr/bin/php
<?php

    public $type;
    public $contents;

    public function __construct($rawToken) {

            $this->contents = $rawToken[1];
        } else {
            $this->type = -1;
            $this->contents = $rawToken;
        }
    }
}
