How can I merge two or more php objects? - php

Question

I have 2 or more php objects that have the same sections. Each section has objects in it. I want to combine these objects together. Since each section has the same title I remove the title of the new object before merging them. My code isn't keeping the proper structure and is adding an unwanted level 'component' to the primary object. Feels like I am missing something obvious but I Can't figure out how to add the new object without the 'component' level.
Object 1 Example
stdClass Object(
[section_1] => stdClass Object
(
[title] => Production
[component_name_68] => stdClass Object
(
[title] => custom component title
[id] => 68
[type] => component_name_68
[subtotal] => 1127.50
[desc] => custom description
)
)
)
Object 2 Example
stdClass Object(
[section_2] => stdClass Object
(
[title] => Production
[component_name_69] => stdClass Object
(
[title] => custom component title2
[id] => 69
[type] => component_name_69
[subtotal] => 1985.50
[desc] => custom description2
)
)
)
Current Code
foreach($this->Details as $section1){
foreach($newinfo as $section2){
if($section1->title == $section2->title){
unset($section2->title);
$section1->{"component"} = $section2;
}
}
}
Current Result
stdClass Object(
[section_1] => stdClass Object
(
[title] => Production
[component_name_68] => stdClass Object
(
[title] => custom component title
[id] => 68
[type] => component_name_68
[subtotal] => 1127.50
[desc] => custom description
)
[component] => stdClass Object (
[component_name_69] => stdClass Object
(
[title] => custom component title2
[id] => 69
[type] => component_name_69
[subtotal] => 1985.50
[desc] => custom description2
)
)
)
Desired Result
stdClass Object(
[section_1] => stdClass Object
(
[title] => Production
[component_name_68] => stdClass Object
(
[title] => custom component title
[id] => 68
[type] => component_name_68
[subtotal] => 1127.50
[desc] => custom description
)
[component_name_69] => stdClass Object
(
[title] => custom component title2
[id] => 69
[type] => component_name_69
[subtotal] => 1985.50
[desc] => custom description2
)
)
)

Answer 1

Might something like this work?
foreach($this->Details as $section1){
foreach($newinfo as $section2){
if($section1->title == $section2->title){
unset($section2->title);
$components = get_object_vars($section2);
// Check to see that only one key is present. Skip if more than one.
if (count($components) > 1) {
continue;
}
$component_keys = array_keys($components);
$component_key = reset($component_keys);
$section1->{$component_key} = $section2->{$component_key};
}
}
}
Basically it seems the issue is determining the key name for the subordinate component. You would have to add your own error checking. For example, I assume the second component will only have the one object, but that may not be true. Perhaps you need to ensure the key begins with the string "component_name", perhaps that is just a placeholder. You would just need to adapt this to your data structure.

Combining Objects sometime is hectic job because we want to keep the object definintion after merging them into single object(parent)
