Just use explode function to split your input according to the spaces. Loop through the array and then print the index number + 1 where the string juice is found.

$string = "i like manggo juice and apple juice";
$parts = explode(" ", $string);
foreach ($parts as $key => $value) {
    if ($value === "juice")
    {
        echo ($key + 1)."
";
    }
}
