如何为我的函数编写测试用例？PHP
我需要为这个函数编写一个测试用例，但我似乎无法正确地得到它。我正在测试我的本地机器，如果这意味着什么如何为我的函数编写测试用例？PHP,php,regex,foreach,preg-replace,str-replace,Php,Regex,Foreach,Preg Replace,Str Replace,我需要为这个函数编写一个测试用例，但我似乎无法正确地得到它。我正在测试我的本地机器，如果这意味着什么 function cleanEncoding($a) // Replace specified foreign character with equivalent english character { $filter = ['"' => '"', '"' => '"', '&' => '&'

正如其他人指出的，您的
str\u replacepreg\u replacereturnforeach ($filter as $key => $value) {
$a = str_replace($key, $value, $a);
}
$a=preg#u replace（“/&#[0-9]*；/”，“”，$a）
然后返回该字符串：
返回$a试试这个，你的代码有一些语法错误

您在$d中替换外来字符，但返回$a。难怪外来字符仍然存在。而且您需要在$d
上执行str\u replace
而不是$a
。是的，他执行str\u replace和preg\u replace操作。
