How do I loop through using foreach for a json decoded array

Question

Array
(
    [id] => 7.8803211967429E+17
    [title] => Example T-Shirt
    [body_html] => 
    [variants] => Array
        (
            [0] => Array
                (
                    [id] => 6.4266704147271E+17
                )

            [1] => Array
                (
                    [id] => 7.576504846442E+17
                    [product_id] => 7.8803211967429E+17
                )

        )

    [options] => Array
        (
            [0] => Array
                (
                )

        )

)

I need to get IDs from each main array. I get this array from decoding json using:

<?php

    set_time_limit(0);
    $json = file_get_contents('imarasoft.net/imarasoft/abd/WebHook/response.txt');
    $arrays = json_decode($json, true);
    print_r($arrays);
    foreach ($arrays as $array) {
        echo $array["id"];
    }

How can I print ID using foreach? i HAVE EDITED THE QUESTION AND HAVE GIVEN THE FULL ARRAY FORMAT

Actually I will get many jsons appended to a file. All I need is to get IDs from each of those json..for that I decode it and try to get the value in ID but I couldnt For now I have only one json in the txt file — Abdul Rahman, Mar 28 '18 at 08:17
@AbdulRahman please can you put this information in your question, it is better to give the full 'story' rather than giving it in snippets in the comments. — Script47, Mar 28 '18 at 08:18
foreach($array as $key ) { print_r($key['id']); //print_r($key); } Thisis not giving what I needed — Abdul Rahman, Mar 28 '18 at 08:21
What did you try and what didn't work? If you have ONE array just do `$array['id']` and if you have MULTIPLE array, just do a `foreach($multiple_array as $array) { echo $array['id']; }`, no? — Mickaël Leger, Mar 28 '18 at 08:21
@AbdulRahman Please edit your question and add what you tried and what you get so we can have better idea of your problem — Mickaël Leger, Mar 28 '18 at 08:23
@AbdulRahman if it didn't work it's because the "array" you show us is not the "right" array you get, please edit your question and add the "real" array, a screen shot of how it look I don't know and show us what you tried and what result you get please — Mickaël Leger, Mar 28 '18 at 08:29
I'm just thinking, did you tried `foreach($arrays as $obj) { echo $obj->id; }` ? Maybe you don't have array but obj I don't know — Mickaël Leger, Mar 28 '18 at 08:30
@MickaelLeger : i HAVE EDITED THE QUESTION WITH MY FULL ARRAY.. i NEED TO ECHO "7.8803211967429E+17" — Abdul Rahman, Mar 28 '18 at 09:57
@AbdulRahman well, if you only need the first id `echo $array['id']` should works no? — Mickaël Leger, Mar 28 '18 at 10:04
@AbdulRahman he can't works since your array in ONE array, so just do `$arrays = json_decode($json, true); echo $arrays['id']` — Mickaël Leger, Mar 28 '18 at 10:08

If you are getting more number of elements in the array then you can use below snippets. This foreach loop go through all the arrays and gives value of each array's key. Here you can any value like title, id, vendor, product_type etc...

If you want access id inside variants then use below code.

$json = file_get_contents('http://imarasoft.net/imarasoft/abd/WebHook/response.txt');
$arrays = json_decode($json, true);
foreach ($arrays["variants"] as $array) {
    echo $array["id"];
}

And if you only want to access root id then you just need to do only one line snippet.

echo $arrays["id"];

Illegal string offset 'id' – Abdul Rahman Mar 28 '18 at 09:53

Do you want get id inside variants? – Pankaj Makwana Mar 28 '18 at 10:04
If I understand a foreach is useless since his JSON array is ONE array, he has multiple array only in `$array['variants']` so he should do `echo $array['id']` and he will get `7.8803211967429E+17` as he wants, no? – Mickaël Leger Mar 28 '18 at 10:06
If you want to get root `id` then you can use `$arrays['id']`. If you want to use `id` inside `variants` then you have to use `foreach($arrays["variants"] as $array){ echo $array["id"]; }` – Pankaj Makwana Mar 28 '18 at 10:08
nO, i NEED TO GET THE id FIELD VALUE – Abdul Rahman Mar 28 '18 at 11:30
Which `id` `{ "id": 788032119674292900,` or `"variants": [ { "id": 642667041472714000,`? – Pankaj Makwana Mar 28 '18 at 11:32
You can just use `echo $arrays["id"];` this statement, this will work. Check I have updated my answer – Pankaj Makwana Mar 28 '18 at 11:38
@AbdulRahman, worked my answer? Please upvote and accept the answer if it helped. if still didn't work then let me know – Pankaj Makwana Mar 28 '18 at 11:51
