How to check if a word exists in a sentence
For example, if my sentence is $sent = 'how are you'; and if I search for $key = 'ho' using strstr($sent, $key) it will return true because my sentence has ho in it.
What I'm looking for is a way to return true if I only search for how, are or you. How can I do this?
Answer
You can use the function preg-match that uses a regex with word boundaries:
if(preg_match('/\byou\b/', $input)) {
echo $input.' has the word you';
}
