Combining an array based off value - php

Question

Alright, I have been pulling my hair out on this one! I have tried an SQL call to add the features to a product, but since the product is one row and the features are not it creates a new row for each product. I thought I could add both to an array and join them based off the product ID. Here are the arrays
array
0 =>
array
'id_product' => string '9' (length=1)
'name' => string 'Brady ENV100 MAXX Enhanced Sorbents' (length=35)
'number_sold' => string '6' (length=1)
'link_rewrite' => string 'brady-env100-maxx-enhanced-sorbents' (length=35)
'id_image' => string '27' (length=2)
1 =>
array
'id_product' => string '10' (length=2)
'name' => string 'Brady GP100 MAXX Enhanced Heavy Pad' (length=35)
'number_sold' => string '3' (length=1)
'link_rewrite' => string 'brady-gp100-maxx-enhanced-heavy-pad' (length=35)
'id_image' => string '29' (length=2)
array
0 =>
array
'id_product' => string '9' (length=1)
'name' => string 'Height' (length=6)
'value' => string '5' (length=1)
1 =>
array
'id_product' => string '9' (length=1)
'name' => string 'Width' (length=5)
'value' => string '5' (length=1)
2 =>
array
'id_product' => string '9' (length=1)
'name' => string 'Depth' (length=5)
'value' => string '5' (length=1)
3 =>
array
'id_product' => string '9' (length=1)
'name' => string 'Weight' (length=6)
'value' => string '5' (length=1)
4 =>
array
'id_product' => string '10' (length=2)
'name' => string 'Height' (length=6)
'value' => string '10' (length=2)
I have looked at many tutorials, but can't seem to get anything to work. What I would like it to look like is
array
0 =>
array
'id_product' => string '9' (length=1)
'name' => string 'Brady ENV100 MAXX Enhanced Sorbents' (length=35)
'number_sold' => string '6' (length=1)
'link_rewrite' => string 'brady-env100-maxx-enhanced-sorbents' (length=35)
'id_image' => string '27' (length=2)
name' => string 'Height' (length=6)
'value' => string '5' (length=1)
'name' => string 'Width' (length=5)
'value' => string '5' (length=1)
'name' => string 'Depth' (length=5)
'value' => string '5' (length=1)
and so on.

Answer 1

You can try this
For your product array do this:
$result = array();
foreach ($mainItems as $item){
$result[$item["id_product"]] = $item;
}
Then for each of your attribute arrays
foreach($attributes as $val){
if (array_key_exists($val["id_product"], $result)){
$result[$val["id_product"]][$val["name"]] = $val["value"];
}
}
You should end up with an array that looks like
[9] => array(
[id_product] => 9
[name] => "Brady ENV100 MAXX Enhanced Sorbents"
[number_sold] => "6"
[link_rewrite] => "brady-env100-maxx-enhanced-sorbents"
[id_image] => "27"
[Height] => 5
[Width] => 5
[Depth] => 5
),
[10] => array(
[id_product] => '10'
[name] => 'Brady GP100 MAXX Enhanced Heavy Pad'
[number_sold] => '3'
[link_rewrite] => 'brady-gp100-maxx-enhanced-heavy-pad'
[id_image] => '29'
