我已经扩展了一个类别的PSR-2嗅探集.现在检查执行两次 – 即使我的chid类是空的.
为什么？怎么做正确？
编辑：
我现在有一个想法为什么：可能的嗅探器可以从实际调用的标准规则到最高(直接或不包括的)父标准的自动化处理规则.它完全执行它们. (is is so？)OK,但该怎么办？如何覆盖父规则集 – 替换他们的类,但是定制它们,并停用单个规则？

背景信息：
我想为Zend Framework 2项目编写一个PHP CodeSniffer规则集. Zend Framework 2 Coding Standards的大约一半已经在PSR-2嗅探文件夹中实施.
目前的目标是不实施整个Zend标准.我想从PSR-2开始,也可以逐步添加/实现其他Zend规则.
问题是,PSR-2嗅探器还包含几个支票,这违反了Zend标准.所以我必须覆盖这些嗅闻.示例：/path/to/PHP/PHP/CodeSniffer/Standards/Squiz/Sniffs/Functions/MultiLineFunctionDeclarationSniff.PHP(在关闭中需要功能关键字后的空格). PSR-2是基于PSR-1,它使用这个嗅探.所以我必须覆盖它们.
排除一个嗅探可以很容易地用排除方向进行,例如：
<?xml version="1.0"?>
<ruleset name="ZF">
<description>...</description>
<!-- Include the whole PSR-2 standard -->
<rule ref="PSR2">
<!-- to disable a single error -->
<exclude name="Squiz.Functions.MultiLineFunctionDeclaration.SpaceAfterFunction"/>
<!-- or to disable the whole sniff -->
<exclude name="Squiz.Functions.MultiLineFunctionDeclaration"/>
</rule>
...
</ruleset>
代替
<?xml version="1.0"?>
<ruleset name="ZF">
<description>...</description>
<!-- Include the whole PSR-2 standard -->
<rule ref="PSR2"/>
...
</ruleset>
覆盖=排除嗅探创建另一个.
