Strpos with exact matches

Question

I have a function in php which I would like to perform a simple search on a string, using a kw as the search phrase, and return true if found.

This is what I have no

You can use word boundaries \b:

if (preg_match("/\b".preg_quote($kw_to_search_for)."\b/i", $search_strings[$i])) {
    // found
}

For instance:

echo preg_match("/\bProfessional\b/i", 'Prof'); // 0
echo preg_match("/\bProf\b/i", 'Prof');         // 1

/i modifier makes it case insensitive.
