PHP strpos - search only full words [duplicate]

Answer 1

Try this regex.

$re = '/\b[Aa]ny\b/';
$str = 'Company any any. Any, ';

If(preg_match_all($re, $str, $matches, PREG_SET_ORDER, 0)){
        //string contains word
 }

// Print the entire match result
var_dump($matches);

The word to pattern can be made with

$pattern = "/\b[" . strtoupper(Substr($word,0,1)) . strtolower(Substr($word,0,1)) . "]" . Substr($word,1);
