If I understand you correctly, then you want to find a substring in the string. This can be done using the strpos method.

// строка в которой вы ищете слово $mystring = 'Текст с 4 словами'; //слово, которое вы ищете $findme = 'Текст'; $pos = strpos($mystring, $findme); if (false === $pos) { echo 'слово ' . $findme . ' не найдено'; } else { echo 'слово ' . $findme . ' найдено в позиции ' . $pos; }

In addition, you can solve this problem using regular expressions. Or you can write your own method to search for substrings in the string.
But for simple things, I use exactly strpos.
