Search with PHP inside MongoDB - php

Question

Im trying many days now to select data from this db
[1]: https://i.stack.imgur.com/QA34L.jpg
I want to print for example all comments
echo $comment['username']." | "; \ Alex | Alex
My php code so far:
[![$m= new MongoDB\Client ("mongodb://127.0.0.1/");
$db = $m->stores;
$collection = $db->storeinfo;][1]][1]
$storez = $collection->find(array("Products.pTHUMBNAIL" => $pThumb));
$o=1;
$afm=array();
foreach ($storez as $stor) {
$afm[$o] = $stor['AFM'];
$record = $collection->findOne(array(
"AFM" => $afm[$o],"Products.pTHUMBNAIL" => $pThumb));
foreach ($record['Products'] as $pro){
if($pThumb == $pro['pTHUMBNAIL']){
echo $temp = $pro['pID']." ";
foreach($pro as $pro1['pCOMMENTS']) {
foreach($pro1 as $com['Comment']) {
var_dump($com['Comment']);
/*
foreach($com as $comment) {
echo $comment['username'];
}
*/
}
}
}
}
$o += 1;
}
It seems that i just cannot find the correct foreach to loop through my Comment array
var_dump output:

Answer 1

What about this?
After echo $temp = $pro['pID']." ";
foreach($pro['pCOMMENTS'] as $comments) {
foreach ($comments['Comment'] as $comment) {
echo $comment['text'];
}
}
You used foreach() bad: the index should be added to the first parameter, not in the 'as' part.
Also it helps if you use more clear variable names. That doesn't take too much, but makes it more readable and easy to debug.

Answer 2

After echo $temp = $pro['pID']." ";
foreach($pro['pCOMMENTS'] as $comments) {
foreach($comments as $comment) {
echo $comment['text'];
}
}
