Can anyone point out mistake in the following code?

<?php $colors =array('red','blue','green'); echo $colors[2]; ?>


//Place your code below this comment
$colors =array('red','blue','green');
echo $colors[2];


This code appears to work fine here -> http://phptester.net/ from PHP version 5.3 and up. What errors are you getting?

Arrays in php are zero based index so in your array red would be $colors[0], blue $colors[1], and green $colors[2].

Thanks Julian Gutierrez for your help :) I figured it out, I was getting confused between the second value and key value.
