the above output is a result of print_r($count['abc]);
it shows nothing when i do print_r($count['abc']['title'])

Answer 1

You would need to use the numeric key as well: $abc[0]['title'].
In other words, you've got an array with array members of an array type which use numeric keys, in which each of those members are arrays which use associative keys to access values. So you need to access each array in $abc to get to the array which contains your title values.
EDIT
If you're trying to loop through these values, you would need to loop through each array. Such as:
$c_abc = count($abc);
for ($i = 0; $i < $c_abc; $i++) {
echo "{$abc[$i]['title']}<br/>";
}

Answer 2

Read about php associative arrays....you will have you goal achieved
try this:
foreach ($array as $i => $values) {
print "$i {\n";
foreach ($values as $key => $value) {
print " $key => $value\n";
}
print "}\n";
}

Answer 3

To access you array variables, the right way is like this
$count['abc'][0]['title']
However, in your title, you are asking about Array keys as variables?
Actually this does not need to be related with CI.
A simple example
$array = array ( "hi" => "bye");
extract( $array);
//it will make "hi" a variable :: $hi = "bye"
echo $hi; // will output bye

Answer 4

Heres structured solution
$data = Array(
[abc] => Array
(
[0] => Array
(
[id] => 1
[title] => hello 12
[meta_keyword] =>
[meta_description] =>
[tags] => sdfgdfg
[status] => draft
[body] => dsfdsf dfdsafsdfsdfsdf
[photo] => images/blog/nari.jpg
[raw] => nari
[ext] => .jpg
[views] => 0
[video] =>
[categoryid] => 5
[subcatid] => 7
[featured] =>
[pubdate] => 2011-06-17 03:39:55
[user_id] => 0
)
[1] => Array
(
[id] => 2
[title] => hello xyz
[meta_keyword] =>
[meta_description] =>
[tags] => xcfasdfcasd
[status] => draft
[body] => dfdsafsdf dsfdsf dfdsafsdfsdfsdf
[photo] => images/blog/nari.jpg
[raw] => nari
[ext] => .jpg
[views] => 0
[video] =>
[categoryid] => 1
[subcatid] => 2
[featured] =>
[pubdate] => 2011-06-17 03:43:12
[user_id] => 0
)
)
);
extract($data);
foreach($abc as $value){
echo $value['title']."<br>";
}
