I've searched a lot for this, and found several similar questions, but none quite address what I'm trying to accomplish.
I'm trying to write a code that will search a PHP (multi)multidimensional array to see which subarray contains the unique key value that I have. Then I would like it to return the value of a different key in that same object subarray.
$Arraytosearch = Array(
.
//various other subarrays
.
[fields] => Array (
.
.
.
//I don't know the number of the object subarray
[x] => PodioTextItemField Object (
[__attributes] => Array (
[field_id] => 37325091
[type] => text
[external_id] => id
[label] => ID
[values] => Array (
[0] => Array (
[value] => REF100019 ) )
[config] => Array (
[description] => [settings] => Array (
[size] => small )
[required] => [mapping] => [label] => ID [visible] => 1 [delta] => 2 ) )
.
.
.
//(and so on)
I'd like to write a function that will return "REF100019" by supplying the value of the field_id => 37325091.
Some things I have tried that I couldn't get to work:
foreach
and new RecursiveIterator
although the tutorials I read weren't useful for my case here.
Even though the array looks complicated, I think it will be easy since I already have the field id of the parent array.
Thank you in advance for any guidance or sample codes that will work!
Background: This is a part of the response I get from Podio after submitting a request to their API. I just don't know how to take that response and get the piece I need (the ID) so that I can echo it for users).
EDIT: Thank you Orangepill and Barmar for the support. I tried your code. But was getting an error, which made me realize I hadn't given you the full array. I figured out how to get the Podio response to display in a more readable format (I was reading the full JSON response before from the Podio debug file which was super confusing), and figured out the full array is actually structured as I have shown below.
I then took your code and was able to figure out how to make it work for my scenario (see below). Very proud of myself considering I have never written any code before, but I couldn't have done it without your help! Thanks again!
$Arraytosearch = Array(
[items] => Array(
[0] => PodioItem Object(
[_attributes] => Array(
[fields] => Array (
[x] => PodioTextItemField Object (
[__attributes] => Array(
[field_id] => 37325091
[values] => Array(
[0] => Array(
[value] => REF100019 ) )
Note: For anyone who is new to programming like myself and wants the Podio response (or any JSON string) to display in a "pretty" readable format like above, use the code (from Display an array in a readable/hierarchical format thanks to Phenex):
print "<pre>";
print_r($Arraytoformat);
print "</pre>";
And finally, the full code I used (using Orangepill's answer below) which searches the objects and arrays and gives me what I have been searching for for days now is as follows:
$Arraytosearch = PodioItem::filter(APP_ID, $filterParams);
$fieldID = 37325091;
function getFirstValueByFieldId($fieldId, $Arraytosearch){
foreach($Arraytosearch["items"][0]->__attributes["fields"] as $textitem){
if ($textitem->__attributes["field_id"] == $fieldId){
return $textitem->__attributes["values"][0]["value"];
}}}
$refID = getFirstValueByFieldId($fieldID, $Arraytosearch);
