Question

是否有内置的嗅探来确保

public function foo () {
                   ^----

没有这样的空间。

我无法在任何内置标准中找到它，或者我只是想念它？

您可以轻松扩展或创建自己的标准。这是一个示例，说明如何将请求的功能添加到PEAR标准（默认值）。

<?php
//DisallowSpaceBeforeParenthesisSniff.php

class PEAR_Sniffs_Methods_DisallowSpaceBeforeParenthesisSniff implements PHP_CodeSniffer_Sniff
{
    public function register()
    {
        return array(T_FUNCTION);
    }

    public function process(PHP_CodeSniffer_File $phpcsFile, $stackPtr)
    {
        $tokens = $phpcsFile->getTokens();

        do {
          $stackPtr++;
          $type = $tokens[$stackPtr]['type'];  
        } while ('T_OPEN_PARENTHESIS' != $type);

        if ('T_WHITESPACE' == $tokens[$stackPtr-1]['type']) {
            $error = 'Spaces before parenthesis and after function name are prohibited. Found: %s';
            $place = $tokens[$stackPtr-2]['content'] . 
                $tokens[$stackPtr-1]['content'] . 
                $tokens[$stackPtr]['content'];
            $error = sprintf($error, $place);
            $phpcsFile->addError($error, $stackPtr-1);
        }
    }
}

以下文件位于：/usr/share/php/PHP/CodeSniffer/Standards/PEAR/Sniffs/Methods

示例：

<?php

// test.php
class abc
{
    public function hello ($world)
    {

    }
}

我希望这会对你有所帮助

我可以使用哪些内置代码来确保括号前和函数名后没有空格
