    You can try

    $words = array('Word1','Word2','Word3');
    $text = "Lorem Ipsum is simply dummy text of the printing and typesetting industry.";
    echo wordInString($text,$words);
    echo wordInString($text,$words);
    

    Output Example

    Lorem Ipsum is simply dummy Word1 text of the printing and typesetting industry.
    Lorem Ipsum is simply dummy text of the printing Word2 and typesetting industry.
    

    Function Used

    function wordInString($text,array $words) {
        $textNew = array();
        $p = mt_rand(0, substr_count($text, " "));
        $tok = strtok($text, " 
    \t");
        $x = 1;
        while ( $tok !== false ) {
            $textNew[] = $tok and $x == $p and $textNew[] = $words[array_rand($words, 1)];
            $tok = strtok(" ");
            $x ++;
        }
        return implode(" ", $textNew);
    }
