正则表达式，匹配部分单词后与外卡

Question

Let me preface this by saying that I suck at regex badly, I've maybe used it 4-5 times in my life.

Let's assume I have the following array:

$array = array(
    1 => 'ReactorCraft:reactorcraft_block_modelreactor', 
    2 => 'f5b2289c-c1aa-4498-9673-271be0aada6c',
    3 => 'A word'
)

I want to perform a preg_match on each element(already taken care of) with a pattern that will match ReactorCraft, and only that, followed by whatever, I don't particularly care what comes next, I'm only interested in the word ReactorCraft.

I've tried a very simple, and probably wrong, pattern:

'/[^ReactorCraft*]/i'

'/[\\bReactorCraft\\b]/i'

And that's about all my knowledge when it comes to regex.

Any nudging in the right direction is more than appreciated.

Answer 1

matching a specific string with Regex is simpler that it seems:

preg_match("/ReactorCraft/u", $searchText)

That'll match it essentially. If you want to make sure it's at the front of the sentence:

preg_match("/^ReactorCraft/u", $searchText)

You might want to consider strstr and strpos which might be faster.
