Task 2 of stripos not passing

I have tried this a lot but its not working. Basically its asking for us to fix the error like needle in the haystack. But as in my example its not. why? the $var1 and $var2 both starts with R, hence meeting the condition of finding R. Also if i want to write the code down, how can i put it to explain. myself before if <br> " //if var1 starts from R and is true then do this"

index.php 
<?php

    $var1 = "Rocky Road";
    $var2 = "Raspberry";
    $initial = "R";

    if (!stripos($var1,$initial) == 1 && stripos($var2,$initial) == 1) {

        echo $var1 . " and " . $var2 . " both start with " . $initial . ".";

    } else {

        echo "Either " . $var1 . " or " . $var2 . " doesn't start with " . $initial . "; maybe neither of them do.";

    }

?>

It uses a 0 based index, meaning it begins counting at 0 so the R's would be at position 0. Change the 1's to 0's and it should give you the alternate condition.

Shane Meikle Thanks! and what about if i want to understand the code in plain english, would i say something like "if var1 starts from R and is true then do this"?

Yes, that would be about right for the first condition (before the else)

The other thing you have to use is ===. If you use == a return of 0 is the same as false and your code may not work properly. This function returns an integer value for the position of the searched term or false if the letter is not there. If the search character is the first letter, it returns 0 which is equal to false if you use == and not ===.
