[SOLVED] Appending to lower levels of multidimensional array

[gordon142]

I'm sure there must be a simple solution, but I've scoured the net and come up blank. I have a three-dimensional array. I want to append a new array to the third level. In other words, it would be:

array > array > array

          array      array

                      new_array_here

 

If I simply do:

$3darray = array('value1');

it appends it as a new array on the second level of 3darray, but I can't find any way to append it further down than that…

Would this do the job?

 

$array = array(array('value1'));

[EDIT] Correction. That Won't. This will:

 

// Level 1
$array = array('array1','array2');

// Level 2
$array[0] = array('value1','value2');

// Level 3
$array[0][0] = array('sub_value1');

Gives you:

 

Array
(
    [0] => Array
        (
            [0] => Array
                (
                    [0] => sub_value1
                )

            [1] => value2
        )

    [1] => array2
)

OK, that is almost perfect, except that that code you posted seems to create a NEW array on the second level, then another array within that one. Reading back I did not actually make this clear in my initial posting, but what I want to do is to create a new third-level array within an existing second-level array:

 

existing_array > existing_array > existing_array

                                                new_array_here

 

The above tree is now an exact representation of my arrays and what I want to do with them. You might ask why I would need a third-level array at all if I have only a single second-level array. The reason is that after the array structure is properly created, the entire thing is going to be run through json_encode. For the json to parse properly for my uses, I need the three levels of arrays. Many thanks.

this seems easy enough, but without seeing your actual array I can only give an educated guess

$array;//this is your full array
$array[0];//this is the second level of your array
$array[0][0];//this is the third level of your array

to add a new entry to the third level just do
$array[0][0][] = $new_array;
//where new_array is the array that is being pushed into the 3rd level of your array

 

is that what you're looking for?

You can always use the next() function it will get the next level of the array for you.

 

$test = next($yourarray)
echo $test[0];
echo $test[1];

Still not getting it to work.

 

Here is the code I'm running (the variable values stripped from the script, as they add nothing to this example):

 

<?php
$final_output = array( 'Departure Locations' => Array ( '0' => Array ( 'name' => $stop_location, 'time1' => $next_arrival, 'direction1' => $bus_direction, 'time2' => $second_arrival, 'direction2' => $bus_return, 'weekendservice' => $weekend_service ) ) );

$final_output[0][0] = array( 'name' => $stop_location, 'time1' => $next_arrival, 'direction1' => $bus_direction, 'time2' => $second_arrival, ' direction2' => $bus_return, 'weekendservice' => $weekend_service );
print_r($final_output);
?>

 

Here is what it returns:

Array ( [Departure Locations] => Array ( [0] => Array ( [name] => Templeton [time1] 6: 00 PM => [direction1] => null [time2] 7: 04 PM => [direction2] => null [weekendservice] => true ) ) [0] => Array ( [0] => Array ( [name] => Law School [time1] => 5: 43 PM [direction1] => To Lewis and Clark [time2] => 6: 05 PM [ direction2] => To Pioneer Square [weekendservice] => true ) ) ) 

 

Here is what it SHOULD return:

Array ( [Departure Locations] => Array ( [0] => Array ( [name] => Templeton [time1] => 6: 00 PM [direction1] => null [time2] => 7: 04 PM [direction2] => null [weekendservice] => true ) [1] => Array ( [name] => Law School [time1] => 5: 43 PM [direction1] => To Lewis and Clark [time2] => 6: 05 PM [direction2] => To Pioneer Square [weekendservice] => true ) ) )

Use

 

$final_output[0][]

 

instead of

 

$final_output[0][0]

[gordon142]

Use

 

$final_output[0][]

 

instead of

 

$final_output[0][0]

 

Unfortunately, in this instance that produces output completely identical to the output of $final_output[0][0].

[gordon142]

I believe I've figured it out. Never could get stuff to properly append at the third level, but I can achieve the same final product by creating the arrays separating, the stacking them one at a time, like so:

 

<?php
$levelone = array();
$leveltwo = array(array( 'name' => $stop_location, 'time1' => $next_arrival, 'direction1' => $bus_direction, 'time2' => $second_arrival, 'direction2' => $bus_return, 'weekendservice' => $weekend_service ));
$leveltwo[] = array( 'name' => $stop_location, 'time1' => $next_arrival, 'direction1' => $bus_direction, 'time2' => $second_arrival, 'direction2' => $bus_return, 'weekendservice' => $weekend_service );
##print_r($leveltwo);
$levelone['Departure Locations'] = $leveltwo;
print_r($levelone);
?>

 

Which outputs:

Array ( [Departure Locations] => Array ( [0] => Array ( [name] => [time1] => [direction1] => [time2] => [direction2] => [weekendservice] => ) [1] => Array ( [name] => [time1] => [direction1] => [time2] => [direction2] => [weekendservice] => ) ) ) 

 

Which is what I want. Cool.
