This is the array:
Array
(
[0] => Array

[product_details] => {"5f93f983524def3dca464469d2cf9f3e":{"id":"110","qty":1,"option":"{\"color\":{\"title\":\"Color\",\"value\":null}}","price":1400,"name":"Foot Massage","tax":null,"image":"http:\/\/acme.dev\/uploads\/product_image\/product_110_1_thumb.jpg","coupon":"9","book_date_":"2017-04-19","book_date_name_":"wed","start_timeslot_":"09:00:00","end_timeslot_":"10:00:00","has_already_rescheduled":0,"discount_":"0","rowid":"5f93f983524def3dca464469d2cf9f3e","subtotal":1400}}

What I need is to create a new simple array containing the values from all the "id" elements.
Hope this simple foreach will be helpful for you.
Solution 1: Try this code snippet here
$result=array();
foreach($array as $value)
{
$array= json_decode($value["product_details"],true);
$result[]=$array[key($array)]["id"];
}
print_r($result);
Here we are using array_column to extract product_details then we are using to array_map to iterate over $personalDetails which contain all the JSON's then we are using to key function which will return first key of the array, and through that key we are accessing, its id.
Solution 2: Try this code snippet here
<?php
ini_set('display_errors', 1);
$array = Array
(
0 => Array
(
"product_details" => '{"5f93f983524def3dca464469d2cf9f3e":{"id":"110","qty":1,"option":"{\"color\":{\"title\":\"Color\",\"value\":null}}","price":1400,"name":"Foot Massage","tax":null,"image":"http:\/\/acme.dev\/uploads\/product_image\/product_110_1_thumb.jpg","coupon":"9","book_date_":"2017-04-19","book_date_name_":"wed","start_timeslot_":"09:00:00","end_timeslot_":"10:00:00","has_already_rescheduled":0,"discount_":"0","rowid":"5f93f983524def3dca464469d2cf9f3e","subtotal":1400}}'
),
1 => Array
(
"product_details" => '{"2723d092b63885e0d7c260cc007e8b9d":{"id":"109","qty":1,"option":"{\"color\":{\"title\":\"Color\",\"value\":null}}","price":700,"name":"Body Massage","tax":0,"image":"http:\/\/acme.dev\/uploads\/product_image\/product_109_1_thumb.jpg","coupon":"","book_date_":"2017-04-18","book_date_name_":"tue","start_timeslot_":"09:00:00","end_timeslot_":"10:00:00","has_already_rescheduled":0,"discount_":"0","rowid":"2723d092b63885e0d7c260cc007e8b9d","subtotal":700}}'
),
2 => Array
(
"product_details" => '{"a3c65c2974270fd093ee8a9bf8ae7d0b":{"id":"108","qty":1,"option":"{\"color\":{\"title\":\"Color\",\"value\":null}}","price":3000,"name":"Alo","tax":0,"image":"http:\/\/acme.dev\/uploads\/product_image\/default.jpg","coupon":"","book_date_":"2017-04-21","book_date_name_":"fri","start_timeslot_":"10:00:00","end_timeslot_":"12:00:00","has_already_rescheduled":0,"discount_":"0","rowid":"a3c65c2974270fd093ee8a9bf8ae7d0b","subtotal":3000}}'
),
3 => Array
(
"product_details" => '{"a3c65c2974270fd093ee8a9bf8ae7d0b":{"id":"108","qty":1,"option":"{\"color\":{\"title\":\"Color\",\"value\":null}}","price":3000,"name":"Alo","tax":0,"image":"http:\/\/acme.dev\/uploads\/product_image\/default.jpg","coupon":"","book_date_":"2017-04-12","book_date_name_":"wed","start_timeslot_":"08:00:00","end_timeslot_":"10:00:00","has_already_rescheduled":0,"discount_":"0","rowid":"a3c65c2974270fd093ee8a9bf8ae7d0b","subtotal":3000}}'
)
);
$personalDetails= array_column($array, "product_details");
$result=array_map(function($value){
$array=json_decode($value,true);
return $array[key($array)]["id"];
}, $personalDetails);
print_r($result);
Output:
Array
(
[0] => 110
[1] => 109
[2] => 108
[3] => 108
)
You "product_details" seems to be a JSON string. Loop through your array, decode the JSON and store the "id" in a new array.
you may use array_map & array_value to achieve this,
here is a quick example, and you need to modify it to be fit with your needs :
$ar = [
0 => ['product_details' => '{"5f93f983524def3dca464469d2cf9f3e":{"id": 3}}'],
1 => ['product_details' => '{"2723d092b63885e0d7c260cc007e8b9d":{"id": 8}}'],
2 => ['product_details' => '{"a3c65c2974270fd093ee8a9bf8ae7d0b":{"id": 5}}'],
3 => ['product_details' => '{"a3c65c2974270fd093ee8a9bf8ae7d0b":{"id": 1}}'],
];
$ar = array_map(function ($value) {
return array_values(json_decode($value['product_details'], true))[0]['id'];
}, $ar);
print_r($ar);
live demo : https://3v4l.org/koXee
use array_column and json_decode
$new_one = array_column($array,'product_details');
$new_array=[];
foreach($new_one as $key=>$row)
{
foreach(json_decode($row,true) as $key1=>$row1)
{
$new_array[]=$row1['id'];
}
}
print_r($new_array);
Try this code, live demo
print_r(array_column(array_map(function($v){return current(json_decode($v));},array_column($array, 'product_details')), 'id'));
