How would you echo the second value in the array?

<?php

//Place your code below this comment $integer_one = 1; $integer_two = 2; $golden = 1.618; $bool = true; $colors = array('red', 'blue', 'green'); echo $colors['blue']; print_r($colors);

?>

index.php 
<?php

//Place your code below this comment
$integer_one = 1;
$integer_two = 2;
$golden = 1.618;
$bool = true;
$colors = array('red', 'blue', 'green');
echo $colors['blue'];
print_r($colors);

?>

Arrays are 0 indexed, so if you echo $array ( [0] ); will echo the first value. So, echoing the second value requires ......

Ted,

Not going to edit your post, but to access an array, you'd use the brackets [ ] not the parentheses. you would thereby use echo $array[0] for the first value in the array.

Cheers!

Of course you are right. That was my first instinct but I second guessed myself. Edited to reflect it correctly. I also learned that {} are interchangeable with []. http://php.net/manual/en/language.types.array.php

Seth,

Go with what Ted has stated but remember, that is if you are using the default numbered indexes like it is using in the example. You can also name the keys within the array. If you do that, you'd reference the name you used when creating the array:

<?php

$myarray = array('key1' => 'val1');
echo $myarray['key1'];

?>

Cheers!
