在字符串中搜索关键字并在单词周围添加HTML标记

I not new to programming but I am new to PHP. I need to write a function that takes in a string, checks it against a known list of key words and if those key words are found, then it adds HTML tags around that word, while leaving the rest of the string intact. I really don't know a lot of PHP but here's the shell I have

function check_me($text)
{
    $result=$text;
    return $result;
}

How can I check the string $text for key words and wrap HTML tags around them?

    If you have all the keyworks setup in an array, or read them from a file into an array you can simply use the str_replace function.

    $keywords = array(
        "dog",
        "cat",
        "bunny"
        );
    $string = "The cat is sleeping on the couch";
    $string = str_replace($keywords, "elephant", $string);
    //Outputs "The elephant is sleeping on the couch"
    

    Read more on the PHP Manual for str_replace.
