How to output the first data in an array.

drustar

Go here to see what I'm talking about. All data are being encased w/ an array.

<?php
$id = $HTTP_GET_VARS['id']
$content[0]="Some content";
$content[1]="Some content part II";
echo "

";
echo "$content[$id]";
"

?>

Obviously, what happens here is nothing is being outputted because it's waiting for $id to have a num value.

I've tried conditionals and that didn't work. I'm not familiar w/ the syntax so it's possible that it's wrong.

if ($id == undefined) {
$id = 0;
echo "$content[$id]";
} else {
echo "$content[$id]";
}

I am basically trying to initialize $id to have a value of 0. The way I have it set-up above does not work. Any help would be appreciated. 😃

<?
$id = $_GET['id'];

$content[0] = "foo";
$content[1] = "bar";

echo "<!-- HTML Starts Here -->";

if($id == '') // maybe if(empty($id)) but not sure
{
    echo $content[$i];
}
else
{
   echo $content[0];
}

echo "<!-- HTML Ends Here -->";

note:
html comments start with <!-- not <--
?

Thanks for the reply. I think that one worked.

if (empty($id)) {
echo "$content[0]";
} else {
echo "$content[$id]";
}

PHP is so much fun. Haha.
