Able to see a variable in print_r()'s output, but not sure how to access it in code
I want to 'echo' a little bit more nested object.
I saw several posts to this question - but this is freaking me out.
I got an Array/Object named 'arrResult' and the print_r(arrResult) output is:
Array
(
[status] => stdClass Object
(
[code] => 0
[message] => Success
)
[result] => Array
(
[0] => stdClass Object
(
[base] => stdClass Object
(
[id] => 3
[created] => 2012-11-11 12:11:07
[start] => 2012-11-11
)
[pos] => Array
(
[0] => stdClass Object
(
[id] => 4
[invoices_id] => 3
[article_id] => 1
[quantity] => 1
[unit] => Monate
[pos_txt] => Paketname
)
)
[summ] => stdClass Object
(
[net] => 2.52
[discount] => 0
[tax] => 0.47899159663865
[gross] => 3
[rounded_net] => 2.52
)
)
[1] => stdClass Object
(
[base] => stdClass Object
(
[id] => 2
[created] => 2012-11-11 12:10:39
[start] => 2012-11-11
)
[pos] => Array
(
[0] => stdClass Object
(
[id] => 3
[invoices_id] => 2
[article_id] => 2
[quantity] => 1
[unit] => Monate
[pos_txt] => Paketname2
)
)
[summ] => stdClass Object
(
[net] => 5.04
[discount] => 0
[tax] => 0.95798319327731
[gross] => 6
[rounded_net] => 5.04
)
)
)
)
I want to echo all [pos].
Something like 'echo arrResult[result][0][pos][0]->pos_txt', 'echo arrResult[result][0][pos][1]->pos_txt',...
I thought about this:
foreach ((array)$arrResult['result'] as $key => $contract) {
foreach ($contract as $key => $objPos){
echo $objPos->pos_txt;
}
}
My brain doesn't get it.
Can someone help me with this?

Answer 1

You can use
echo "<pre>";
foreach(array_map(function($v){ return $v->pos ;}, $data['result']) as $list)
{
foreach($list as $objPos)
echo $objPos->pos_txt,PHP_EOL;
}
Output
Paketname
Paketname2

Answer 2

Use xdebug extension, it's something what you must have for development anyway, it slightly changes how var_dump works and I believe it will solve your problem
see xdebug documentation

Answer 3

$num = count($arrResult['result']);
for ($i=0; $i <= $num; $i++) {
echo $arrResult['result'][$i]->pos[0]->pos_txt;
}
