如何正确覆盖 PHP Code嗅探器规则集中的规则/嗅探器，并避免重复检查代码

我已经扩展了PSR-2嗅探集的一个类。现在检查执行两次 - 即使我的 chid 类是空的。

为什么？以及如何正确做到这一点？

编辑：

我现在知道为什么：嗅探器可能自下而上地处理规则集 - 从实际调用的标准的规则集到最高（直接或间接包含）父标准。它显然完全执行它们。（是这样吗？好吧，但是该怎么办？如何覆盖父规则集 - 替换它们的类但自定义的类并停用单个规则？

叫：

背景资料：

我想为 Zend Framework 2 项目编写一个 PHP CodeSniffer 规则集。大约一半的 Zend Framework 2 编码标准已经在 PSR-2 嗅探文件夹中实现。

现在的目标不是实现整个 Zend 标准。我想从PSR-2开始，也许可以逐步添加/实现其他Zend规则。

问题是，PSR-2嗅探还包含一些检查，这些检查违反了Zend标准。所以我必须覆盖这些嗅探。示例：/path/to/php/PHP/CodeSniffer/Standards/Squiz/Sniffs/Functions/MultiLineFunctionDeclarationSniff.php（闭包中 function 关键字后需要空格）。PSR-2基于PSR-1，它使用这种嗅探。所以我必须覆盖它们。

        <!-- or to disable the whole sniff -->
        <exclude name="Squiz.Functions.MultiLineFunctionDeclaration"/>
    </rule>
