This is the array:

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
)

Is array_map faster than foreach? Or it really doesn't matters.
foreach is faster
you don't need to use array_column here, json_decode($value['product_details'],true); will do the trick :)

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);

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);

Hi bro, it's my fault. I didn't notice inner is a json string. I edit my answer, check it.

Try this code, live demo

print_r(array_column(array_map(function($v){return current(json_decode($v));},array_column($array, 'product_details')), 'id'));

You "product_details" seems to be a JSON string. Loop through your array, decode the JSON and store the "id" in a new array.

Agree with Tom's comment above. So here's an explanation to a possible solution. Implementing the code shouldn't be that hard.
