Adding two values of two different arrays

[GothyStitch]

I'm attempting to add together two values of two different arrays.

the arrays are handled as strings.

$dlist = $text2[0];
$blist = $text[0];

$text2[0] holds the value of 13 but is viewed as a string.
$text[0] holds the value of 22 but is viewed as a string.

so I try to use settype(); to convert the values to integers so that I can perform mathmatical equations with the values, but first checking to make sure that the values are indeed considered strings. And then trying to perform a simple addition with the two variables.

if (is_string($dlist)) settype($dlist, "int");
if (is_string($blist)) settype($blist, "int");
$newval = $blist + $dlist;

echo "blist equals $blist";
echo "dlist equals $dlist";
echo "newval equals $newval";

Now $newval should have the value of 35, but instead $newval always ends up having a value of 0.

here's the full script I have at the moment with comments.

    if ($text2[1]==1) { $state2 = "Active"; } else { $state2 = "Down"; } // sets the state of the dialup stream

Here's the part that gives me problems, and I think it's due to variable type, but I don't really know.

$dlist = $text2[0];
$blist = $text[0];
$dlist2 = intval($dlist, 10);
$blist2 = intval($blist, 10);
$tlist = ($dlist + $blist); 

Then things work fine:

    // Song info and total listeners
    echo "<div id='r1'>DJ Name Goes Here (coming soon)</div>"; // DJ's Name - Need to find a way to set this
    echo "<div id='r2'>$text[6]</div>"; // Song title 

And then right here is where it displays all the wrong info:

    echo "<div id='r3'>$dlist2 $blist2 $tlist/125</div>"; // Total listeners 

Then the rest is fine:

    // Broadband stats
    if ($er) { echo "<div id='r4'>$er</div>"; } else { echo "<div id='r4'>$state</div>"; } // Stream state
    echo "<div id='r5'>$text[0]/$text[3]</div>"; // Listeners
    echo "<div id='r6'><a href='http://ss3.myshoutcastserver.com:8142'>128kbps</a>, audio/mpeg</div>"; // URL for Stream

    // Dialup stats
    if ($er2) { echo "<div id='r7'>$er2</div>"; } else { echo "<div id='r7'>$state2</div>"; } // Stream state
    echo "<div id='r8'>$text2[0]/$text2[3]</div>"; // Listeners
    echo "<div id='r9'><a href='http://ss3.myshoutcastserver.com:8140'>24kbps</a>, audio/mpeg</div>"; // URL for stream

Ok, I got it working

here's what I got:

Not sure why doing it that way worked and the other way didn't, but I'm not going to complain if it's working!

All I did was this and it started working for me:

$dlist = $dlist{strlen($dlist)-1}; // this makes it work, not sure why
$blist = $blist{strlen($blist)-1}; // but if it works, why complain?
