1You could use regular expressions as its better for word matching compared to
2strpos, as mentioned by other users. A strpos check for are will also return 
3true for strings such as: fare, care, stare, etc. These unintended matches can 
4simply be avoided in regular expression by using word boundaries.

6A simple match for are could look something like this:
7
8$a = 'How are you?';
9
10if (preg_match('/\bare\b/', $a)) {
11    echo 'true';
12}
