php array returning same values in loop - php

Question

I am trying to loop through each key but i am facing a problem of same value repeating inside for each loop
Here is example of my current code and result (click here)
here is my code so far
<?php
$data2 = array(
'category_name' => '33287*100*prescription*1,32457*1250*lab*1'
);
$result = array('0' => (object)$data2);
foreach ($result as $key => $category) {
$category_name = explode(',', $category->category_name);
}
$newresults=[];
foreach ($category_name as $key) {
$category->category_name = $key;
$newresults[]=$category;
}
$result=$newresults;
$newresults=[];
$category->items_count = 0;
foreach ($result as $key => $value) {
list($sale_key, $sale_value) = explode('*', $value->category_name);
// $category->items_count += count($sale_value);
$newresults[]=$category;
}
$result=$newresults;
i am expect the result should be
Array
(
[0] => stdClass Object
(
[category_name] => 33287*100*prescription*1
[items_count] => 0
)
[1] => stdClass Object
(
[category_name] => 32457*1250*lab*1
[items_count] => 0
)
)

Answer 1

The bug is that you're relying only on the last version of $category after you've finished looping it earlier - you'd have to be using it within the loop where it's assigned, in order to get each value in turn, or you could use $value from your last foreach loop.
But as a general observation, this code has way too many loops etc. just for processing one array in the way you've requested. Here's a much simpler version:
$category_name = '33287*100*prescription*1,32457*1250*lab*1';
$category_name_arr = explode(',', $category_name);
print_r($category_name_arr);
$newresults=[];
foreach ($category_name_arr as $cat) {
$newresults[] = (object) array("category_name" => $cat, "items_count" => 0);
}
print_r($newresults);

If you still need to be able to support multiple lines of input, you can do it like this, by just merging the exploded arrays before you process them:
$data = array(
'33287*100*prescription*1,32457*1250*lab*1',
'33222*900*prescription*3,22233*1200*lab*2',
);
$category_name_arr = [];
foreach ($data as $category_name)
{
$category_name_arr = array_merge($category_name_arr, explode(',', $category_name));
}
print_r($category_name_arr);
$newresults=[];
foreach ($category_name_arr as $cat) {
$newresults[] = (object) array("category_name" => $cat, "items_count" => 0);
}
print_r($newresults);

Answer 2

adding $category = new stdClass();
foreach ($category_name as $key) {
$category = new stdClass();
$category->category_name = $key;
$newresults[]=$category;
}
