Please Helop meIn Form.php

<form action="update.php" method="post">
<input type="text" name="siteid" value="<?= $b ?>" />
<input type="submit" name="subjoin" value="Update">
</form>

sorry to say that, but this is a poor designed solution & database model.

concated data inserted into a field is not flexible if you want to update, retrieve data, search, order-by , join with another table and get related data without hardcoding the results.

the solution would be a new table, where you store the ID's in new rows associated with a selectionID.

please give me mini example of updation and how many PHP pages I need. I am new to PHP.

@furqan219 - before your post next please read forum rules. I seen multiple instances of same question all over the PHP forum and also post hijacking. I would normally merge these posts together but at this stage something like that would be disastrous so I will leave them be.

you have to use $_REQUEST instead of $_POST because $_REQUEST support for both method$_POST AND $_GET .
if still problem the use
print_r($_REQUEST);
it show you all the parameters which send on this page.
