是否有运算符来比较PHP中的相似性？ [英] Is there an operator to compare likeness in PHP?

问题描述

正如你在MySQL中看到的那样，有一个LIKE =''％something％''"


我想知道在PHP中是否有办法做到这一点？


谢谢：）

As you see in MySQL there is the "LIKE =''%something%''"

I was wondering if there was a way to do this within PHP?

Thanks :)

推荐答案

最接近的是strstr（），用于搜索字符串中的字符串

The closest is strstr() which searches for a string within a string

I认为一个更好的功能是 preg_match（）！唯一需要注意的是，您需要使用正则表达式。

I think a much nicer function to try is preg_match()! The only caveat is that you will need to use regular expressions.

除非您需要，否则不要使用正则表达式。正则表达式需要更长时间才能运行并消耗更多内存。我今天早些时候回复了一个关于这个问题的回忆，你可以看到我的测试结果< LINK REMOVED>

Don''t use regular expressions unless you need them. Regular expression take longer to run and use up more memory. I just replied to a convo about this earlier today, you can see my test results <LINK REMOVED>
