                    [user_id] => 0
                )

for example if i want to echo out title I would do echo $abc['title'] but it's not working pls help,

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/>";
}
