push certain key/value into existing array - php

Question

I'm trying to put data into from:
[comments] => Array
(
[count] => 2
[data] => Array
(
[0] => Array
(
[idcomments] => 1
[from] => Array
(
[idusers] => 1
[username] =>
[full_name] => AndrewLiu
)
[text] => testing this comment out
)
[1] => Array
(
[idcomments] => 2
[from] => Array
(
[idusers] => 1
[username] =>
[full_name] => AndrewLiu
)
[text] => more comments yeah
)
)
)
I have something like this:
while($row = $SQL_products -> fetch(PDO::FETCH_ASSOC)){
$json['data'][] = array(
"comments" =>array(
"count"=>$SQL_ccount[0],
"data" => array($SQL_comments->fetchAll(PDO::FETCH_ASSOC),
"from" => array($SQL_comments_from->fetchAll(PDO::FETCH_ASSOC)))
),
);
}
But it doesn't fall into the from. Not sure what the right syntax is to get $SQL_comments_from into data such like the example above.
This is what I'm getting
[comments] => Array
(
[count] => 2
[data] => Array
(
[0] => Array
(
[0] => Array
(
[idcomments] => 1
[from] => 1
[text] => testing this comment out
)
[1] => Array
(
[idcomments] => 2
[from] => 2
[text] => more comments yeah
)
)
[from] => Array
(
[0] => Array
(
[idusers] => 1
[username] =>
[full_name] => AndrewLiu
)
)
)
)
I'm trying to get "from" into the "data". The example I provided does not make the "from" go into the other "from" (thats right under idcomments)
Thanks in advance!

Answer 1

Your data field uses data from SQL_comments_from and $SQL_comments_from mixed together, this should generate what you want.
while($row = $SQL_products -> fetch(PDO::FETCH_ASSOC)){
$from = $SQL_comments_from->fetchAll(PDO::FETCH_ASSOC);
$data= array();
foreach ($SQL_comments->fetchAll(PDO::FETCH_ASSOC as $items){
$data[] = array('idcomments' => $items['idcomments'], 'from' => $from[$items['from']], 'text' => $items['text']);
}
$json['comments'][] = array(
"count"=>$SQL_ccount[0],
"data" => $data;
)
),
);
}
