I am new to php so this may be a simple fix.

I have a text file named 'textt.txt' that looks like this:

South East asia,2222,code1

winter break,3333,code2

my php code looks like this:

<?php       
$x = file_get_contents('textt.txt');
        $y = explode("\r\n", $x);
        $z = $y[0];
    echo $z;
?>

the outcome of this is: South East asia,2222,code1

I would like it to return only: South East Asia.

How can I make this happen?

Thanks!
