i'm trying to output data table with PHP multidimensional array, but i have problem with foreach loop it loops for only one index, it doesn't output next indexes, in my print_r output for $docs

Array
(
    [docs] => Array
        (
            [0] => Array
                (
                    [title] => Rew
                    [imgurl] => http://localhost/site/uploads/2012/07/print.jpg
                    [level_id] => Array
                        (
                            [0] => 2
                            [1] => 3
                        )

                )

            [1] => Array
                (
                    [title] => Second
                    [imgurl] => http://localhost/site/uploads/2012/07/type.jpg
                    [level_id] => Array
                        (
                            [0] => 1
                            [1] => 3
                        )

                )

        )

)

in my php 

$i =0;
foreach ($docs as $doc){
   foreach($doc as $a_doc){
       foreach($doc as $a_doc){

        echo $doc[$i]['title'];         
     }

   }
   $i++;
}

but it doesn't give any output,i would REALLY appreciate if someone could give me some advice.

If the array containing the docs key only has a single element, you can do this:

foreach( $docs['docs'] as $doc ) {
    echo $doc['title'];
}

If it should have more than one entry (besides docs), go for:

foreach( $docs as $entry ) {
    foreach( $entry as $doc) {
        echo $doc['title'];
    }
}

Try this:

foreach($docs as $key => $doc){

    echo $doc['title'];

}

Each $doc that is iterated is an array of doc attributes. The $key in the foreach() loop is the currently indexed key for the currently iterated element in the $docs array.
