如何使用similar_text()改进PHP字符串匹配? [英] How to improve PHP string match with similar_text()?

问题描述

我正在使用 PHP 的 similar_text() 调用来比较两个字符串，但是，我得到的结果不够好，例如，对于我希望看到 100% 的匹配，我得到的最好结果是 80.95%

I am using PHP's similar_text() call to compare two strings, however, I am not getting good enough results, for example, the best I'm getting is 80.95% for a match that I'd like to see 100% on.

我可以使用哪些其他函数将字符串深入到核心?

What other functions can I use to get the strings down to the core?

<!-- Overcast, Rain or Showers compared Overcast, Rain or Showers is 80.9523809524 -->
<!-- Overcast, Risk of Rain or Showers compared Overcast, Rain or Showers is 86.2068965517 -->
<!-- Overcast, Chance of Rain or Showers compared Overcast, Rain or Showers is 83.3333333333 -->

与 similar_text() 相反，所以 0% 表示存在没什么区别.

It's reverse to similar_text(), so 0% means there is no difference.

// <!-- Overcast, Rain or Showers compared Overcast, Rain or Showers is 0 -->
// <!-- Overcast, Risk of Rain or Showers compared Overcast, Rain or Showers is 11 -->
// <!-- Overcast, Chance of Rain or Showers compared Overcast, Rain or Showers is 13 -->
