but that not helping me because the path is different .

when i try login to electrum with different path it will give me another XPub
i try those paths :

Code:

m/44'/0'/0'
m/44'/0'/1'
m/44'/1'/0'
m/44'/0'/0'/0'
...

You made quite a mess here.

The third level of the derivation path is the coin type. (Details here: https://www.oreilly.com/library/view/mastering-bitcoin/9781491902639/ch04.html)
For example, m/44/1 is a test network branch

Your script should be creating a new account for each user, then it ahould be m/44/0/username

Quote

the only one give me right XPub is m/44'/0'/0'

now how i can make electrum generate addresses with the same path i use in my php script

Code:

527/0
528/0
.
.

Each time you change the derivation path after the third level you will get a new xpub. This is why electrum is showing a different xpub.
You can see it in action here: https://iancoleman.io/bip39/

You can change de derivation path and see how the xpub changes.

An xpub will derive all public keys in that branch.
I think that as you generated an xpub in the top level, it contains all those child ones. You are just getting an xpub of child branches. You have those keys in your xpub.

You just need to figure out in which derivation path they are.

Can you give us more information about this script you made?

In your next payments, you should definitely use a professional solution like btcpayserver.org
They have hardware wallet integration and it is free to use

thanks for explaining

about the script :
i install Bit-Wasp/bitcoin-phpLibrary

Code:

composer require bitwasp/bitcoin

and i make new file HD.php :
link for HD.php :

}

after that i include HD.php in my project like this :

Code:

require_once('./HD.php');

$xpub = 'xpub......';
$path = $client_id.'/0';
$hd = new HD();
$hd->set_xpub($xpub);
$address = $hd->address_from_master_pub($path);

where $client_id is client id number
