Same Array Index to own Array

If you want to change it to a 2 layer array just create a variable that holds the first element of the 3 layer array:
somthing like:
var array2D = array3D[0];
Also this bit of code seems like its not necesarry
$html = array($output);
$response = $html;
echo json_encode($response);
unless you need the array to be 3 layers when encoding it to Json. Otherwise just change it to:
echo json_encode($output);
Hopefully I understood your question and was able to help a little.
Edit
The way your foreach loop is currently running you're only creating a new array for each element then adding the same elements to their respective array and finally storing every array inside a new one (1 array with ALL id's, and one with ALL companynames etc...)
to fix it is very simple.
inside your foreach loop the $row variable looks like this:
$row => [idvalue, companyvalue, streetvalue etc....]
it's already an array containing the current $row's data, now all you need to do is directly add it to your $output array.
You're new foreach loop should look something like this:
foreach($employee_query as $row) {
$output[] = $row; // when using [] after a variable you add to that array
}
echo json_encode($output);
if you don't want to use all the data that your query collected you can specify which attributes you want to use like so:
$output[] = array($row['FT.ID'], $row['kundenname'], $row['straße'], etc...);

ANSWER should be like this:
Array
(
[csv_data] => Array
(
[0] => Array
(
[0] => CAM
[1] => Partner
[2] => Division
[3] => Domain
[4] => Year

[8] => 4200
)
)
)

Try this code, this will definitely work for you..
$removeKeys = array();
foreach($data['csv_data'] as $key => $val)///loop through array..
{
foreach($data['csv_data'] as $k => $v)
{
if($val[1] == $v[1] && $key != $k)////check if key 1 matches
{
if(!in_array($key,$removeKeys)) ////check if item is already added or not
{
$removeKeys[] = $k; ///push into removed keys because this is added into matched item
$data['csv_data'][$key][7]+=$data['csv_data'][$k][7];
$data['csv_data'][$key][8]+=$data['csv_data'][$k][8];
}
}
}
}
foreach($removeKeys as $rk)
{
unset($data['csv_data'][$rk]); ////remove all the keys in removeKeys
}
print_r($data['csv_data']);///your desired output...
This will give you :
Array
(
[0] => Array
(
[0] => CAM
[1] => Partner

[5] => Quarter

Retrieving elements from a nested array

if this is really output by print_r then $data[0][1] must be '2014-11-06 11:31:58.781018' . I test it by code:
$data = array(array('1','2014-11-06 11:31:58.781018'));
echo '<pre>';
print_r($data); echo '<br>';
echo 'what we want: '.$data[0][1].'<br>';
otput:
Array
(
[0] => Array
(
[0] => 1
[1] => 2014-11-06 11:31:58.781018
)
)
what we want: 2014-11-06 11:31:58.781018

If you have the $data as an array you can access the value: 2014-11-06 11:31:58.781018 by using,
$date = $data[0][1];

write an array to a multidimensional array read from csv with php

i have the folowing array read from a csv file:
Array
(
[0] => Array
(
[0] => book1
[1] => description1
[2] => category1
[3] => code1
[4] => editor1
[5] => 0
[6] => eur
[7] => out of stoc
)
[1] => Array
(
[0] => book2
[1] => description2
[2] => category2
[3] => code2
[4] => editor2
[5] => 0
[6] => curr2
[7] => out of stoc
)
[2] => Array
(
[0] => book3
[1] => description3
[2] => category3
[3] => code3
[4] => editor3
[5] => 0
[6] => curr3
[7] => out of stoc
)
)
Code :
function read_CSV_raza($rzs_csv) {
$file_handle = fopen($rzs_csv, 'r');
while (!feof($file_handle)) {
$line_of_text[] = fgetcsv($file_handle, 1024, ';');
}
fclose($file_handle);
return $line_of_text;
}
$rzs_csv = 'rzs.csv';
$csv = read_CSV_raza($rzs_csv);
I want to add another array (headers) in order to write this intro another csv file.
EX :
Array
(
[0] => Array
(
[0] => h1
[1] => h2
[2] => h3
[3] => h4
[4] => h5
[5] => h6
[6] => h7
[7] => h8
)
[1] => Array
(
[0] => book1
[1] => description1
[2] => category1
[3] => code1
[4] => editor1
[5] => 0
[6] => eur
[7] => out of stoc
)
[2] => Array
(
[0] => book2
[1] => description2
[2] => category2
[3] => code2
[4] => editor2
[5] => 0
[6] => curr2
[7] => out of stoc
)
[3] => Array
(
[0] => book3
[1] => description3
[2] => category3
[3] => code3
[4] => editor3
[5] => 0
[6] => curr3
[7] => out of stoc
)
)
I tried with array_merge(); array_unshift(); but to no avail, i do not get the results i need.
The cod for writing the array in the new CSV is :
$fp = fopen('rezultate.csv', 'w') or die("Can't open rezultate.csv");
foreach ($csv as $items) {
fputcsv($fp, $items, ';', '"');
}
fclose($fp) or die("Can't close rezultate.csv");
As i am not a programmer any help with this issue would be greatly appreciated.

array_unshift worked for me:
$add = array (
0 => "h1",
1 => "h2",
2 => "h3",
3 => "h4",
4 => "h5",
5 => "h6",
6 => "h7",
7 => "h8"
);
array_unshift($myarray, $add);
And also
array_unshift($myarray, array(0 => "h1", 1 => "h2", 2 => "h3", 3 => "h4", 4 => "h5", 5 => "h6", 6 => "h7", 7 => "h8"));

array manipulation

I have a two column array (array1), for each row of that array I need to compare the value in the 2nd column with a column value in each row of another array(array1) , when they equal I want to append another column value (from array2) to the first array.
in english:
if array1[x][1] = array2[y][0]
then array1[x][2] = array2[y][2]
screen dumps of both arrays

[0] => 1 [1] => 2

Does this work? I'm not sure I'm entirely clear on what you're looking for.
foreach($array1 as $x => $xarray) {
foreach($array2 as $y => $yarray) {
if($xarray[1] == $yarray[0]) {
$array1[$x][2] = $array[$y][2];
}
}
}

foreach ($array1 as &$a1) {
foreach ($array2 as $a2) {
if ($a1[1] == $a2[0]) {
$a1[] = $a2[2];
continue 2;
}
}
}
BTW, you should try to use explicit keys that actually mean something, e.g. $a1['id'] instead of $a1[1]. You'll thank yourself when you look at the code again two months down the road.
And because I threatened to do so:
btwyoushouldtrytouseexplicitkeysthatactuallymeansomethingeg$a1['id']insteadof$a1[1]youllthankyourselfwhenyoulookatthecodeagaintwomonthsdowntheroad ;-P
