Hello reader's I have created a conversion format that can convert array in tree structure. In this code i use while loop but you can either use the recursive also. So here is the function as below:-

function treeze( &$a, $parent_key, $children_key )
{
    $orphans = true; $i;
    while( $orphans )
    {
        $orphans = false;
        foreach( $a as $k=>$v )
        {
            // is there $a[$k] sons?
            $sons = false;
            foreach( $a as $x=>$y )
            if( isset($y[$parent_key]) and $y[$parent_key]!=false and $y[$parent_key]==$k )  
            { 
                $sons=true; 
                $orphans=true; 
                break;
            }

            // $a[$k] is a son, without children, so i can move it
            if( !$sons and isset($v[$parent_key]) and $v[$parent_key]!=false )
            {
                $a[$v[$parent_key]][$children_key][$k] = $v;
                unset( $a[$k] );
            }
        }
    }
}

In the code above every key value have it's own id . Now in this function you have to send three params , First the Array, Second is parentID and last childrenKey

Finally you can access the function as by code below:-

treeze( $SendArray, 'ID', 'Key' );
echo "<pre>"; print_r( $SendArray);
