PHP匹配正则表达式中的多个完整单词

Question

I'd like to match a string for word1 or word but a string like 'this is a testword' should NOT give a match. I'm trying to do preg_match('/^\\b(word|word1)\\b/i',$string) but no luck

Answer 1

I think your problem is the ^ at the start:

preg_match('/\b(word|word1)\b/i',$string);

Note that the ^ denotes the beginning of the string, so you are looking for something that starts with the options you are giving.

Answer 2

如果从RegEx的开头删除^ ，似乎工作正常。
