PHP正则表达式匹配斜杠 [英] PHP regexp match slash

问题描述

我在 regex101 测试了以下正则表达式，它在那里工作.但是，当我尝试在 preg_match 中使用它时，它不再起作用.问题是斜线:我试图转义它，但我无法让它工作.

I have the following regular expression tested at regex101 and it works there. However, when I try to use it inside the preg_match it doesn't work anymore. The problem is the slash: I tried escaping it but I can't get it working.

preg_match("/[<>\\\"'%;()&]/", "my\string");

我应该匹配的字符集是:

The set of characters that I should match are:

< > \ " ' % ; ( ) &

推荐答案

只需使用不同的分隔符:

Simply use a different delimiter:

preg_match("![<>\\\"'%;()&/]!", "my\string");
