类似于在PHP中使用Regex

Question

I've a word, $my_word="MYWORD"; Now, I want to make a regular expression of that, which detects the following cases

--> MY WORD
--> MYWORDS
--> MYWORDSISMINE
--> WORD
--> WORDS

Now, I want to make a regular expression in php using preg_match() which detects the following occurrences.

My Try:

$mycase = str_replace(' ', '|', $my_word); // where $str would be MYWORD
$mycase = (preg_match("/\b(".$mycase.")\b/", $someFuzzyWord)); // $someFuzzyWord is the user entered string which needs to be filter

I had putted the | so that it can detect every word and also tried .* after starting and trailing of a word so that it can be detect a substring.

I think this can help you:

$mycase = str_replace("MY", "", $my_word);
$regex = "(MY)? ?" + $mycase + "S?(ISMINE)?";
$mycase = (preg_match("/\b(".$mycase.")\b/i", $someFuzzyWord));
