Search associative array for specific value based on set variable - php

Question

I'm retrieving some JSON that I am converting to an associative array. The issue that I am having is I am trying to get the email value from the user's who id matches the value that I have already set as a variable.
Here is what the array looks like
Array
(
[object] => list
[data] => Array
(
[0] => Array
(
[object] => pro
[id] => pro_77c9c6a85d814e059a6a2690989bae29
[first_name] => Jane
[last_name] => Doe
[full_name] => Jane Doe
[initials] => JD
[email] => admin#testorg.com
[mobile_number] => 9998761234
[messaging_uuid] => 4547c231c3e7d0ff1796f47b88f166d5
[color_hex] => EF9159
[avatar_url] => /assets/add_image.png
[avatar_thumb_url] =>
[has_avatar] =>
[organization_name] => testorg
[is_admin] => 1
[permissions] => Array
(
[show_company_setup] => 1
[can_see_home_data] => 1
[show_reporting] => 1
)
[is_super_pro] =>
[is_archived] =>
[impersonated] =>
)
[1] => Array
(
[object] => pro
[id] => pro_0fcb8e8610e54c518078db77ced7530e
[first_name] => Robert
[last_name] => Jordan
[full_name] => Robert Jordan
[initials] => RJ
[email] => rj#testorg.com
[mobile_number] => 4547457742
[messaging_uuid] => 0fcb8e8610e54c518078db77ced7530e
[color_hex] => EF9159
[avatar_url] => /assets/add_image.png
[avatar_thumb_url] =>
[has_avatar] =>
[organization_name] => testorg
[is_admin] => 1
[permissions] => Array
(
[show_company_setup] => 1
[can_see_home_data] => 1
[show_reporting] => 1
)
[is_super_pro] =>
[is_archived] =>
[impersonated] =>
)
)
[url] => /pros
)
Im basically trying to match the value that I have set in my pro_id variable
pro_0fcb8e8610e54c518078db77ced7530e
To the 'ID' Key in the array above and get the 'email' value associated to that same array and store for use later in my code.
Here is what I have so far, but no joy
foreach ($proObject as $key => $value) {
if ($key['id'] == $pro_id)
$techmail = $key['email'];
}

From my understanding of your question, and if you want to get only one element, you should be able to use array_search with array_column to get the index of the searched element. Using that you can then access the element and its corresponding email value. If you might expect more than one element I would use array_filter.
One Element:
In short:
$i = array_search($pro_id, array_column($proObject, 'id'));
$element = ($i !== false ? $proObject[$i] : null);
print_r($element["email"]);
Full code:
<?php
$proObject = array(
array(
"object" => "pro",
"id" => "pro_77c9c6a85d814e059a6a2690989bae29",
"first_name" => "Jane",
"last_name" => "Doe",
"full_name" => "Jane Doe",
"initials" => "JD",
"email" => "admin#testorg.com",
"mobile_number" => "9998761234",
"messaging_uuid" => "4547c231c3e7d0ff1796f47b88f166d5",
"color_hex" => "EF9159",
"avatar_url" => "/assets/add_image.png",
"avatar_thumb_url" => "",

"is_admin" => "1",
"permissions" => array(
"show_company_setup" => "1",
"can_see_home_data" => "1",
"show_reporting" => "1",
) ,
"is_super_pro" => "",
"is_archived" => "",
"impersonated" => "",
) ,
array(
"object" => "pro",
"id" => "pro_0fcb8e8610e54c518078db77ced7530e",
"first_name" => "Robert",
"last_name" => "Jordan",

$pro_id = "pro_0fcb8e8610e54c518078db77ced7530e";
$i = array_search($pro_id, array_column($proObject, 'id'));
$element = ($i !== false ? $proObject[$i] : null);
print_r($element["email"]);
?>
Multiple Elements:
In short:
class idEqualsFilter {
private $id;
public function __construct($id) {
$this->id = $id;
}
function __invoke($i) {
return $this->id === $i["id"];
}
};
$elements = array_filter($proObject, new idEqualsFilter($pro_id));
print_r(array_column($elements, "email"));
